Calibration not possible via Mobile app

Morning,

Updated my P1S with AMS to 01.05.03.01 - After every software update I start the calibration process via printer or mobile app (iPhone). On my phone it don’t want to start the calibration process (turning circle and nothing happens).

Can anybody check and agree on it?

Kind regards
Carsten
