Shared SaaS running 19.9.0.4
iOS 12.x, and lower, DEP iPhone would begin setup. User would be prompted to enter organization credentials. User would be authenticated. The Hub app was assigned, so the app would push to device and it would recognize that this was an enrolled device. User information would populate in the app. No need to re-enroll.
iOS 13, the phones are configure the same. I entered my credentials the same way. However, the Hub app does not recognize the device as already enrolled. I see the profile installed. Everything works as expected, except for the Hub app. When I try to enter username and password, it goes through the process as usual. However, it obviously fails to install since the device is already enrolled. The actual error message is: ' Profile Installation Failed. A connection to the server could not be established.'
So, I am experiencing the same problem.
