@hans_martin My experience has been absolutely positive. My banking app works (you can check in the forums for known bank apps that work).

If you already have android, install this app to see what will work:

I did have one app (Business Calendar Pro 2) where the license would not transfer through MicroG.

Some apps that i had previously used Google Login (like Duolingo) required me to reset the password so that i could login without Google.

Sorry for the English.
