@MojangSupport My friend and I are both playing on Xbox, we both downloaded the update yesterday, but it's still throwing up the 'outdated server' message when I try to connect to his realm

Are you still having issues at this time? Sometimes the update can take a bit to push through on Realms. ^TK

Yeah, still having the issue, and another friend is having the same problem. The person whose Realm it is will be in the Realm, will send us pictures to show it, but the two of us trying to get on both still get the 'Outdated Server' message

Has your updates pushed through on your client as of yet? ^Tk

No it has not, still outdated server
