Windows 11 Family Child Accounts Don't Stay Authenticated to XBox App

Hi all,
I have just coming across this issue in the last 48-72 hours for my 2 children who are 11 1/2 and 13 1/2.

Whenever they open the XBox App on Windows 11 they are prompted to Sign In or just Browse the App, they select Sign in and it gives them a "Welcome Back message" and confirm to use that account or sign in with another.  If they close the app and re-open it they are prompted to sign in again.  We have Microsoft Family setup and have tested this across 3 seperate devices and it behaves the same.  If I log into the XBox App though then close it and re-open I stay logged in.

This issue has extended onto causing sign in/authentication issues for games installed/downloaded from the Windows Store/XBox app.  Mainly Minecraft Bedrock, PalWorld and Roblox.

Minecraft Bedrock opens but says they are not signed in.  When you click sign in within a few seconds you get the error message "Drowned"

Roblox Application opens to the Roblox title screen but there is nothing to click on to sign in etc. Just the background picture.

PalWorld looks like its going to start to launch, you see a brief message saying Signing In and Syncing then Palworld shows the error: "The game crashed Error code: (0x8000ffff)" or "Something went wrong launching your game Error code: (0x8007023e)" and occassionally 'Something went wrong launching your game.  Error code: (0x87e10802). 

If I uninstall the version of say Roblox from the XBox and app download and install it directly from the Roblox website it works correctly.

I reloaded my sons computer from scratch and the issue is still there.

Someone mentioned about some recent authentication issues Microsoft have been having.

Any help greatfully received.

Thanks,
