Hi all,
Preview users on the 4.67.15001.0 build should be receiving updates to the 4.67.21001.0 build which should resolve their issue without having to do any PowerShell commands.
Please check the Store>Library>Get Updates to update the Gaming Services. It may take 24-48 hours to see it while it's continuously pushed out, so don't worry if you do not see it right away.
Thank you all for reporting these bugs so the team could resolve them before it hits GA. As Insiders on preview builds, these things tend to happen, so please keep reporting issues as you come across them.
Thanks,
Hayabusa
