JohnHartmann just out of curiosity, did you manage to install it on a secondary profile or on the Owner?
Im asking this because I'm also having trouble installing MBWay on my Pixel 7a.
Spent an hour trying to install it on a separate "Banking" user profile with:
- Google Play Services (with SMS Permission enabled) installed
- With and without "Exploit protection compatibility mode" toggled
I also tried to log in using the QR Code method but that for some reason also doesn't seem to work.
I checked the app logs and I believe this might be the issue:
pt.sibs.android.mbway.mobileui.authentication.smsauth.nomserror.MobileServiceUnavailableErrorActivity
although I have no clue.
I eventually gave up and tried just installing on the Owner profile.
Google Play Services with SMS Permission and it just worked.
No idea why this does not work on a second user profile. Maybe some core "SMS Authentication" feature gets stripped on separate profiles ¯_(ツ)_/¯
If anyone managed to install MBWay on a separate user profile please let me know :)
