SAP Asset Manager - Passcode Policy disabled - Unable to get shared device encryption key

I person built my ain branded Asset Manager. I installed the app and executed onboarding (pressed "Use existent application") - worked OK. I did not person to usage QR code.

Later, I disabled the Passcode Policy successful BTP Cockpit > Mobile Services > Mobile Settings Exchange. The QR codification for onboarding has changed. Now erstwhile I instal branded Asset Manager connected a caller instrumentality and take "Use existent application", the aged passcode argumentation is loaded from BTP (set caller passcode is required). And connected the initializing screen, I get an mistake "Unable to get shared instrumentality encryption key".

With the disabled passcode policy, I person to usage (scan) the caller QR codification (onboarding - fastener "Scan caller QR code"). With caller QR codification onboarding works. But I request onboarding without a QR code.

The lone settings I saw successful the task astir BTP are successful <mdkproject>\BrandedSettings.json. But determination is thing that would person an interaction connected passcode policy.
