    So I have a small update from Microsoft on this, and it's more of a temporary fix from what I understand.

     

    1. Login to https://endpoint.microsoft.com/#blade/Microsoft_Intune_DeviceSettings/DevicesEnrollmentMenu/enrollmentRestrictions
    2. Create a new Device Type Restriction
    3. Give it a name
    4. On "Platform Settings" change "Android Enterprise (work profile)" to BLOCK
    5. Make sure "Android Device Administration" is set to ALLOW
    6. Click Next
    7. Click Next
    8. Under Assignments click Add Group and select the group of users that are signing into devices.
    9. Click through to finish the setup

     

    Wait a few minutes, and reboot the phone, login again.

     

    I'm still trying to find out how to resolve the issue correctly, but this seems to have helped most of the cases I've had issues with so far.

We are having the same issue with Poly C60 conference room phones once updated to firmware 7.0.2.1071. This firmware comes with Teams App 1449/1.0.94.2021022403 and we get the same login loop. I've tried updating to Teams App 1449/1.0.94.2021033002 but problem persists. I have tried both the original web login method as well as the new remote provision/login method and both result in the same login loop.

If I roll the firmware back to 5.9.5.3153 and Teams App 1449/1.0.94.2020121001, I can web login the phone again without issue. I can then fully upgrade the phone's firmware and Teams App version to latest and the phone will stay logged in. However, if I log it out, I can't log it back in as it gets stuck in the same loop.
