SafetyNet was completely disabled by Google in 2025, now the PlayIntegrity API is used, MicroG already supports it.

[anton-sutopo]

You mean this exception is expected for now, and not impact to the application behavior?

exactly
that whole menu needs to be reworked for play integrity, it's kind of a hidden sideeffect of enabling safetynet
