I migrated my Mojang account to Microsoft today and extend my Realm server right away before start the game. and then I run the game and click my realm.
and it said Invalid signature for profile public key. Try restarting your game.
I tried "restarting" like forever. I have no mod or strange launcher thing.
By the way all my friends can connect to my Realm but only me.
Thank you for your report!
