I submitted a ticket and got a reply that this was a known bug but I should submit the ticket in here to help the moderators and developers collect more information.

When I try to connect to my realm, all I get is "Unable to connect".  Power down Xbox and clearing the cache doesn't help.  Tried for a PC and still get the same results.

It's closing in on being down a day now.  I pay to have this, so what compensation will I get back for not having access to what I'm paying for?
