erefewfef I need the banking app, and i don't want to install it on the second user, i need to isolate it on the 2nd user and thinked, that it can be solved by VM.
I am unsure why you don't want to install the banking app installed in this second profile. The Android app sandbox plus isolating the app in a different profile should be isolated enough. Unless you're trying to hide the fact you're using GrapheneOS?
