Hi all, I'm trying to troubleshoot an issue with Proton Calendar.
I had originally installed Proton Calendar version 2.3.X via apk file from their official source here:
Was running it for about a week, and everything has been great. I tried getting it to update via Obtainium, but did not have much luck. Was putting it off as a project to figure out later.
Then today I tried to open the app and it refused to open. An error message appeared (coming from the calendar app itself), telling me to update and offering an "update" and "learn more" button.
This is on the Owner profile, and I do not have Google Services Framework, Google Play Services, or Google Play Store installed on this profile. So as expected, pressing the "update" button doesn't work because it can't find an app store. It threw a 2nd error on top of the 1st, then it faded away and left me stuck in the 1st error again.
The "learn more" button just takes me to the proton documentation site, explaining that outdated releases are eventually barred from functioning for security purposes.
I then tried uninstalling the old version 2.3.X, downloading the latest apk from the link above (version 2.4.5 as of this writing), and installing that. According to GOS, the installation went perfectly. But upon opening the app, I get the login screen, then get the exact same error after a successful login.
I tried installing on a different profile via Aurora Store, and that went fine, app works perfectly normally. But I want this app on the Owner profile specifically, without Aurora / Play / F-Droid. Plus, I'm worried that this issue could eventually recur on different profiles.
I tried restarting the phone, then running through the uninstall-reinstall cycle again, but got the same bad result.
I tried resetting app preferences under Settings -> System -> Reset Options -> Reset app preferences, then doing the uninstall-reinstall cycle. But I got the same bad result.
After trying those things, I tried doing the reinstall cycle again just out of desperation. After attempting to open the apk, I got a new error message: "App not installed because package appears to be invalid."
I tried redownloading the apk from the proton app link above several more times, thinking that the original apk got currupted somehow. But from then on I got the same error, no matter which apk I used. Even the original apk downloaded from my first attempt no longer works, same "invalid package" error.
So somehow my troubleshooting efforts appear to have made the situation worse. Before I could install the app via apk and open it, but hit a wall after a successful login. Now, I can't even install the app via an apk.
How to proceed? Would love to get this back up and running again in the Owner profile.
