Hi! 

I have created a world and hosted it in Realms. Using my Microsoft account (AccountA) I can access this world from PS4, and logging out and back in as AccountA on Switch, I can access it from Switch.

However, if using a different Microsoft account on the Switch (AccountB), I cannot access this Realm,

I have tried

1) using an invite code

2) Finding cross-platform friends, then adding AccountB the Realm's list of Members.

Playing as AccountA on PS4, I can see Account B in the Members section, with a green light next to their name. 

Playing as AccountB on Switch, I can see the Realm to join, but upon joining I get the error 

"You're not invited to play on this server".

Please help! Thanks
