Can't join my bedrock preview realm with error "Blocks between client and server do not match". Other members of the realm get the same error message when trying to join. The realm was joinable before updating the game to the latest version. Tried restoring a backup and uploading a new world to the realm, neither worked.

I'm also experiencing this issue, as I'm sure are many more.
I was able to access my realm from one machine before it unfortunately was automatically updated and I lost access completely.
I hope that 1.21.0.26 will be released soon to address this as I don't believe there is a workaround and we are effectively locked out of our preview realms until this issue is patched.
