Hello, 

I just created a Minecraft account online today for one of my kids (Mac OS). It is the Java edition. My child's friend sent an invite to join their family's Realm and so I accepted for my child. We tried to load the Friend's Realm, but it is stuck on the "Connecting to the realm..." loading screen.... we have tried restarting Minecraft, checked my privacy settings and they appear to be correct... not sure what the issue is... 

One of my other children has been playing online on his Minecraft account for several months (which I set up earlier this year) and had previously joined this exact same Realm of a friend's family. This other child was able to play on the friend's Realm this afternoon without any issues while sitting right beside my other child on another computer who could not connect to the same Realm.

Both computers are Mac OS computers...  

Please help! My child would like to join their sibling and friends on this Realm....
