Teams Rooms devices should only be assigned Teams Rooms Basic or Teams Rooms Pro licenses*.* You can assign up to 25 Microsoft Teams Rooms Basic licenses to Teams Rooms systems in your organization.
In this case, we recommend you see what license your devices have by going to Teams devices in the Teams admin center and see if it still healthy, and then selecting the device category (Teams Rooms on Windows, Teams Rooms on Android, and Surface Hubs) you want to see.
