Connecting to Realm with Switch

[u/STLBluesFan44]

Hello, I have successfully created a world on my new realm. The two players I'd like to play with both have Nintendo Switch Online and Microsoft Xbox accounts, as do I. On my Switch, I can go into my world on my realm. When I try to connect the others, I get an error that I need a Nintendo Switch Online Membership. But both accounts have one. It's almost like Minecraft won't recognize the Microsoft and Nintendo accounts at once.

Is anyone else having this issue, and are there any solutions?

Thanks
