Anyways, I've contacted support again, and this time the answer was different:
Aquatica:
_I asked the other day about the recent update that prevented GrapheneOS users from using the Revolut app. I was assured that the issue will be fixed, but I see online that some support agents are still saying that GrapheneOS is not going to be supported.
This OS is based on Android, it's no different from Samsung OneUI, Xiaomi or whatever other OS based on Android.
The recent update prevents the app from running due to the recent Play Integrity API implementation, which requires the OS to be signed by Google. I was told the team was working on fixing it, but different support channels are saying different things. Can you share some details and if possible an ETA? Thanks._
Revolut
I understand your concern about the compatibility of the Revolut app with GrapheneOS and the Play Integrity API. We have already forwarded your feedback to the team, they will surely look into this matter for you.
Aquatica
_I understand, but I'm looking for a more in-depth answer.
A lot of users have reported this to Revolut, and all of them have received different answers, even myself right now. First, I get told that they are working on it, now it's a forwarded feedback. What exacty is going on here?_
Revolut
I understand the confusion caused by receiving different responses. Our team is currently reviewing the details and I recommend keeping an eye on official Revolut communications, such as updates on the Revolut website or app store listings, for any announcements regarding app compatibility with different operating systems.
Aquatica
No ETAs, right?
Revolut
Unfortunately, I don't have any specific ETAs or updates regarding this issue at the moment.
Aquatica
_Honestly it's frustrating to get told that I should check social media to find out when I'll be able to use my app without issues.
If I log out now, I won't be able to login anymore, this is bad._
Revolut
I understand your frustration, and I apologize for the inconvenience. Your feedback is valuable, and I'll ensure it's passed on to the relevant teams. Thank you for your patience.
I also wrote a negative review after this (and rated the support experience the lowest score), but have yet to receive a reply.
