I don't get an invitation with Minecraft bedrock edition. (report)

I wanted to multiplayer with a friend on Minecraft bedrock edition, and I received an invitation from a friend, but the invitation is not displayed.

It's a shame to join a friend's world and play.

Please correct it.　I'm in trouble because I can't multiplayer.

By the way, when you send an invitation, it seems to reach the other party.
But I don't get invitations from other people.
