I am experiencing a problem where I am unable to accept an invitation to a friend's Realm on Minecraft for Windows 10.
Whenever I attempt to accept the invitation, I get the message
You cannot play online multiplayer through Xbox Live because of how your account is set up. This can be changed in your privacy & online safety settings on Xbox.com
I have checked through my Privacy & Online Safety settings, and have verified that my
Join multiplayer games option is, in fact, set to
Allowed. Despite this, I am still unable to accept the invitation.
