Guys, thank you very very much for your feedback
amazing community
I am also going to send a formal complaint to revolut

I lost access cause I log out from the app and deleted the user holding the revolut app ( was in need of reorganizing users )
Process I was following: 1 create a new user, 2 install the mirrors provided by graphene apps of play services and play store, 3 install froid or droidify, 4 get aurora, 5 install revolut.
Something weird is happening now when I try to install aurora from droidify, is never getting installed, or at least, if the package is installed, is never displayed any icon to execute it in a reasonable time, so will try to let the system cook it for some time and check.
It seems Fdroid is providing a better installation of aurora at this moment than droidify, is straightforward installation.
The same was happening with aurora to install revolut, and already read a mate here that is recommending to just wait until aurora gives the notification that its installed, otherwise it seems we are interrupting the installation ( I will try that )

So far with the new update to the specified below, still not working
com.revolut.revolut
version 10.56.1
versionCode 1005604910

will test this thing of letting the installers work for few minutes just to see if that waiting time makes a difference.
thank you everyone for your time again,

    fid02 I assume you were already logged in when you updated the app to the latest version?

    Correct

      I got a response from Revolut, more accurately stated as an acknowledgement that they have forwarded my complaint:

      Thank you for reaching out to us!

      I immensely appreciate your patience as we are currently experiencing an increased demand, which, due to circumstances beyond our reach, has left some messages unanswered.

      I appreciate your feedback. I will share your comments with the team. We will see if we can improve this in our future developments. Please be assured that our product expert teams are continuously working to improve user experience. If you have any issue or any suggestions please write to us here and we will do our best to assist you.

      I really appreciate your understanding.

      Basically a canned response, but there was no expectation of getting anything besides that.

      Yes, that is what everybody thinks when they hear "Play Integrity"...

      Update:

      The issue was that I needed to first remove the Revolut app in the Owner profile.
      After I did that, I installed the older version 10.54 using apkmirror on my Private Space, managed to login and later updated it using the sandboxed PlayStore in the Private Space. The latest uptodate app now works without any issue.

      Hope that helps anyone looking for a workaround.

          I have been struggling to deal with Aurora and its installation prior to install revolut from it
          from installation error conflict with another package that is the same (despite it was a fresh new user evironment)
          problems downloading the revolut apk prior to installation
          problem when installing revolut app, saying that apk is corrupt

          on any circumstance, even if I am waiting long time letting Aurora to install, the Revolut app is showing same.

          I will start revolut from a crappy phone have hanging arround home, and will send the complaint

          will give the bank a certain time to turn on this, if they do not change, will close the account and will find another solution

            actually not, I havent
            I dont have a google account for years... I dont even know how to log in or iniciate the thing...

                rigel24 I wanted to move Revolut from my Owner profile to the Private Space.

                The issue was that, because I didn't uninstall Revolut on the Owner profile first, I couldn't install an older version on the Private Space, since android requires that apps with the same ID on multiple profiles need to be at the same version.

                So I uninstalled the up to date one on the Owner profile (the one that has the issue mentioned in this thread) and installed an older version using apkmirror.com.
                Versions older than 10.56 don't have this "custom firmware restriction", and if you are already logged in, you can still use the latest revolut version on GrapheneOS..
                So I logged in using revolut 10.54 installed through apkmirror inside the Private Space and after that, I updated the app using the Play Store. Everything works.

                    krysor not on my side with 10.56.2: still working on the profile where I already was logged in but NOT working on a separate profile where I am trying to setup the app ("custom firmware restriction" error message during login).

                      krysor 10.56.2 just got released. Still no difference?

                      Still no dice.

                      On the note of contacting Revolut, it appears that their Play Store responses are quickly dismissing reports which solely complain that the app is blocking custom Android OSs. Reports which describe GrapheneOS are getting actual engagement, in the sense that they want to contact the reporter and open a ticket. So it's desirable if people describe to them why the message about the OS being blocked for safety reasons should not apply to GrapheneOS because of its considerable security features compared to other Android OSs out there. I suspect that Revolut support has been instructed to simply reject reports that complain about "custom OSs" being blocked, while regarding GrapheneOS they might be more unclear on whether the blocking is a mistake or not, so they're actually forwarding our feedback to the developers.

                      I actually think using the term "custom OS" is not even correct in the context, so I don't think we are hiding anything by not using the term: simply being an alternative OS to larger Android-based OSs does not make it more "custom" than, say, Google's stock PixelOS.

                      A review where Revolut dismisses a report, and reveals that the blocking is due to trying to fulfill some certification:

                      I love revolut and been a customer for 5-6 years. But all of the sudden, they decided to stop letting custom Android OS users use the app. This means not being able to use this bank, as everything relies exclusively on this app. I hope they change their mind about this, because it's not helping anyone, specially loyal customers.

                      Revolut response:

                      We understand that this decision is not ideal and that it affected some of our customers. However, to certify our security protocols and that our app functions as intended we had to take this difficult decision. We sorry this affected you and understand your decision not use our services through the currently supported OSs.

                        I just moved to grapheneos with two new pixel9 sadly recognized this issue.... on other hand all fine... so moving fw revolut works just fine on other pixel9 supported roms like calyxos (beta) and under crdrid. I do understand GOS is a more secure rom than the others but I do not think it is a matter of security... Any idea by the developers for this issue other than canned answers? Are they trying to find out the solution already?

                          604959zd

                          Thank you! This works just fine! Hope there will be a normal solution soon. Till than this makes me a hope to migrate into grapheneos fully.

                            PGOSUW2P9 so moving fw revolut works just fine on other pixel9 supported roms like calyxos (beta) and under crdrid.

                            Which version of the app did you install there?

                            Edit: because it would be interesting to know if Revolut doesn't actually manage to block other less secure operating systems. But if you installed and signed in with a version older than 10.56 that would explain why you weren't blocked.
