missing certificate
Hello everyone,

we use over 20 T56A, but unfortunately only 30% are working well, and 70% devices are getting error: you can't sign in because your device is missing a required certificate.

I compared all the settings and found no differences. Even working devices don't have any certificates at all:

Firmware Version 58.15.0.122
Hardware Version 72.0.1.0.1.0.17
Company Portal Version 5.0.4927.0
Teams Version 1449/1.0.94.2020111101

Thank you for any suggestions.
