German Payback app is not working since some time

Deleted: cache + data → deinstalled app → enabled location → reinstall app

Message: “Diese Anwendung kann nicht ausgeführt werden, da die Umgebung unsicher ist…”

Translated somehow: app is not executed because of insecure environment (it’s the only app…all installed banking apps working fine…)

ADB error log shows following lines

In my case iode’s privacy features are super on-top capability for an older phone which lost vendor support some time ago…but I still like to continue the use to avoid electronic waste.

And the loyalty apps are running in the work profile using “shelter”.

you enable all google and safety things in microG?

Yes, and can replicate this on 2 phones - but no Google account configured.

There are comments in Playstore that since an update approx. 2 months ago that the app won’t work anymore on free OS.

OK, a app problem
May happen
