We are in the same version which is 1.16.1 and we care not playing on the BETA we are both on the same console which is Xbox one Bedrock edition. As I am writing I tried to invite her and the same problem seems to be happening, I invite, her character appears and then shortly after disappears and says That she has left the game.
I’ve had the same problem particularly with brown pandas and now it’s a bug in 1.15 and 1.16.1

It affects Realms like this: Kids need to be signed into Xbox live to access realms. Kids then want to play Minecraft when not connected to WiFi so I need to sign them out of Xbox live every time they leave house.
I am not signing them in and out every time they want to play so cancelling Realms as it's to much effort.... please fill in blanks as i'm not going step by step.
Come on Microsoft and fix this, I'm canceling realms as it's useless if the kids iPad's crash ever time they don't have WiFi. Maybe I'll come back one day.
Ok it seems as though the issue was her being a member of a realm effecting her ability to join the world once she left the realm she has not had any issues with joining
