I am having issues to connect to my friends multiplayer games either to join on their world or having them going on mine. I've checked security features to make sure that there is nothing blocking there but I still having the issue. 

  My two friends are using iPad with iOS 16.6 and I am using an iPhone with iOS 16.6. They can join each other worlds but I can't join them, and they can't join mine.

We have each other as friends and as favorite. In the past we were able to join each other worlds, a little bit glitch but worked. On the last year we cannot anymore.

Please help me fixing this issue.
