lbschenkel This is still true. I installed GPS to make MitID work, then after signup, I uninstalled GPS and the app works for authentication. Last time i updated the app though, with GPS installed, it broke the app.
So my conclusion from tests are that GPS is needed for initial launch/after update - but not in general use
The jump from web to app though does only work sometimes, which is why it makes sense to set method to numbers instead of QR code
Hope this helps
