Minecraft Pocket Edition 1.16.10: Cannot join friend’s world

Hello Microsoft team and community,

I have been constantly trying to join my friend’s multiplayer world on Minecraft, but it says “Unable to join game,” or something along those lines. We are both Xbox friends, and our settings do not block these attempts. We are both in a close location,
so we are a few minutes away from each other’s house. It only works on rare occasions on the same internet connection, but that’s it. Is there anything possible you guys can do or tell me to do to be able to stop this occurring issue? It would mean a lot.

:)
