Interesting - I have exactly the same problem when using AusweisApp2 with FP3+ and eOS. I do not believe that it is a question of how to place the card correctly into the near of the NFC chip… I tried all possible positions, always the same problem despite 100% charge, detached cover… obviously the NFC connetion gets started at first (vibration, some initial functions) but then always interrupted. I have read that some devices deactivate NFC automatically if it is active longer time than necessary for payments… ? So the interaction starts but always is stopped by the device like a timeout… ? Any users here with success using AusweisApp2 on FP3/3+?
