I have had something similar (with a different brand), the problem was with device´s firmware.
But first, make sure that both the Teams Room device's firmware and the Teams app are updated to the latest versions. Manufacturers often release updates to fix bugs and improve stability, so this could help.
Next, check the network connection of the device. An unstable and unreliable network can also cause this. If there are any network drops or interruptions, it could lead to sign-out problems.
Take a look at the account configuration on the device. Make sure it's set up correctly and doesn't have any conflicting settings that could cause the sign-out issue.
Also, check the power and restart settings. Ensure that the device's power settings are appropriate, and it's not going into sleep or hibernation mode, as this might trigger sign-outs.
If you've tried these steps and the issue persists, consider reaching out to the manufacturer's support team. They might beallready familiar with this problem.
