Can't Connect to Realms

It seems if i try to accept a realms invite, it sends me this error:
"You cannot play online multiplayer because of how your Microsoft account is set up. Review and change your privacy settings at aka.ms/accountsettings"
This is odd to me, because in my account settings, join multiplayer games is set to allow, and I can accept the realms invite on other platforms, just not Nintendo Switch. Please fix, because I really want to join my friends again.
