I keep having that same issue and get that same message. I don't have issues accessing the marketplace using my x-box or my laptop but I haven't been able to access the marketplace on my android phone.
Is there a way to share saved games between devices? I own 2 Xbox ones, windows 10, Java version and the android version. I'd like to be able to play my saved game on either console or my windows 10 or android device since they are all the same versions now without using realms to transfer the saved game to each device?
So you mean I have to drop out of the beta on all systems in order to use realms?
No, thank you. The updated pack works great.
