Ilya Bukshteyn thank you for the update. However this is for enterprise environments where they have to manage these devices via SCCM/InTune to comply with corporate policies. We now have multiple clients with over 400 devices that now will not sign into teams.
Salvador Gomes from Microsoft has said that you do not publish when an MTR version becomes unsupported. I think that we should be told when an MTR version will stop working in advance so clients are able to plan to update their devices to the latest MTR version.
We have to accept that some clients have extremely strict security and need to test/process any changes for weeks before they can go live. these clients i am assuming now have no choice but to update to the latest version otherwise they will not have any working rooms. Again this process takes time and you cannot create a package and send this out in a matter of minutes to a whole enviroment.
In future can we have some updates before a version will stop working
