A friend does not receive an invitation to the world

We wanted to play with a friend in the world together. In order to prevent the other nkito from joining, I set in the network game settings "by invitation only". But when I send an invitation to a friend, it just doesn't come to him. The same situation is with me, no invitations come from a friend. If we play without an invite-only setup, it can enter my world normally. We did not change the settings of the xbox profiles, that is, the invitations should come. And yes, the problem is not only with my friend. None of my friends receive a notification that I have invited him, and vice versa. Consequently, they also do not have my world on the "friends" tab.
