I’ve updated my Xperia 10 II to 5.0.0.55. Now the german android app Payback cannot be started anymore and claims that the environment is unsafe. Other apps like banking apps still work without problems. I already tried to reinstall the app without change in the behavior.
It could be because of Play integrity, but the app was working in 4.6 so it is a regression. I also tried older versions from 2024 of the app in 5.0 with the same results, so it is about the SailfishOS update.
The actual version of payback is also not working on 4.6. There was a bug-report here in the forum already. My ex, who has a Xperia 10ii also with 4.6, complained also about the not-anymore-working payback-app.
I see nothing in this thread that it is over once you upgraded. You can downgrade android apps, but you have to uninstall and reinstall the older version. I already did that without success. For Revolut the issue is just that after downgrade and data loss you have to reregister your device, but for Payback you just would need to login using a password.
As older versions that surely were working have the same error now on 5.0.0.55 it has to be something about the SailfishOS update.
