Minecraft for Windows 10 was updated to 1.14.60, and no longer is able to log in to the current Bedrock Server at 1.14.32.
Contacted Microsoft Support and they are unable to help, and forwarded me to Mojang for help. Needless to day there is no easy way for end users to block the Windows Store update or downgrade to previous version. As a result nobody can log into the server any longer as of today.
Finally server updated to version 1.14.60.5. It took hours for this update to come to server after being pushed to all clients. This is even with me being proactive and actively trying to download the server to see what version I can get.
It would be nice if Mojang and Microsoft somehow avoid this kind of problem in future? maybe make the client backward compatible, release a backward compatible server first, or just try to release these at the same time? I think the server should take priority as it may affect many more users at the same time.
