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.
I have the same issue with the payback app but it appeared after updating the Payback app to a newer version than 24.12.0500.
When downgrading to 24.12.0500 the app opens again and is usable.
Unfortunately this version isn’t available anymore at Aptoide. But a downgrade is still possible using the Aurora Store with the following steps:
1.) Install Aurora store
2.) Search there for the payback app
3.) Push the Icon with the three dots on the right top
4.) click “select version” (or “Version auswählen”)
5.) in the dialog where you are asked for the version you want, type ‘1000034256’ and then “check”/“prüfen”
6.) a working version is offered to be installed
Nevertheless, is there are a way to configure the Android subsystem more restrictive to pretend the apps to run on a safer device?
The apps use frameworks such as DexGuard. They execute several system file checks and then decide if its safe or not. Since all that trash is closed source, we will never know what goes wrong.
