Identified - The cause of hang when using the UC Flex option has been identified as an incompatibility between certain versions of the Windows 11 operating system and Microsoft Teams Rooms (MTR). This is due to the fact that Microsoft's Windows Update services the OS in the recovery partition, while MTR is updated through the Store. The Store does not service MTR in the recovery partition. This results in the OS / US version incompatible combination that can cause the recovery process to hang.
It should be noted that the failure can be seen when manually running a recovery locally on a Win11/MTR device. Here is Microsoft's KB article that includes a link to a offline update script: https://learn.microsoft.com/en-us/microsoftteams/rooms/manual-update This script should be ran before running the recovery process. It updates the MTR version in the recovery partition.
Our fix plan for the ThinkSmart Manager UC Flex Option:
In 25.1, we will reenable UC Swap for all devices except those on Win11 23H2. Release window is 2/8-2/22
In 25.4, we will reenable UC Swap for all devices - part of the process will run the fix provided by Microsoft above to remotely update the MTR version instead of using the version stored in the recovery partition. Release window is 4/12-4/26.

Investigating - The ability to remotely switch MTR-W licensed device to Zoom and back to MTR will be temporarily disabled due to a compatibility/mismatch issue between the UC client and Windows OS updates versions. We will provide updates on the status for enabling this feature as they are available.
