This is back online again now.
My kids can play on their switch and use their Microsoft accounts to get to our realm.
Has anyone heard back from Mojang?
They seem to be brushing this under the carpet and nothing as gone out to the user base, my bug got closed as invaild because I selected the wrong platform!
Seriously! I report one of your platforms is down and you close the ticket because I put the wrong platform, update the ticket yourself thats what good customer service is!!!
I can get on realms again thanks.
