Realms: Over the last few days, we have deployed fixes that should resolve the current issues for most users. We know that some user are still getting errors, and we are continuously working to restore operations to normal for everyone. ^FT

Hi. The problem you've described sounds like a temporary issue. Please try again later. ^DS

I have this same issue but it's been over 24 hours, the realm owner is unable to update their client and the realm still hasn't updated.
