I'm enrolling Samsung A70 devices with a staging user with QR code mode, Android Enterprise COPE, (WS1 2001)
I have set All Settings --> Devices & Users --> Android --> Android EMM Registration --> Enrollment Settings --> Work Managed Enrollment Type --> device based.
After 9 devices I get the error "Failed to register Google Account".
I also tried to create a new staging account and delete the restriction profile, but this time the error appeared on the thirteenth device.
Could it be a connectivity problem?
Or do you think you need a new Android EMM Registration?
