Playing around with AE, with Samsung it’s going pretty smoothly. Stepping out of that and testing with a Moto G4 Plus device, when I setup for this, I get a strange error. Both devices are enrolled into the same location group so get the same profiles and policies (EAS, WiFi, etc).
When I open Gmail, this is fine. When I open Google Contacts, no errors but doesn’t sync the contacts across. When I open Google Calendar, I get the error “This change isn’t allowed by your administrator”.
