This has been happening quite often when I want to log into a friends Java Realm.I have already accepted the invite into the realm and have already spent quite a few hours in it.

MC boots up normally through the launcher. Home screen has the blue diamond on the MC Realms button. "CLICK" MC Realms page shows an ad for either a Free Trial, Buy your own or both.

There is no [X] to get out of the ad. Sometimes there is just a blank screen. Sometimes the Invite Envelope and News buttons come up. I cannot enter my friends realm with this ad in the way.

I have clicked [back] to the home screen, [mc reams], [back], [mc relams], etc. It does not go away.

I have gone from windowed to fullscreen, fullscreen to windowed, etc. It does not go away.

I have tried the F11 trick. It does not go away.

I have quit the game itself, logged back in. It does not go away.

What seems to be the problem and why has this not been fixed since 1.15ish? Any other advice for a Mac user?
