The error when connecting to the world of xbox live friends that existed in the original version persists in the beta of the new version, it is very difficult to join the worlds and more if your Wi-Fi connection is not fast enough. Therefore, regarding the last one, I would like to add that it would be very good to be able to connect to the worlds using mobile data (although it may carry additional charges) for those people who have a low-quality Wi-Fi connection or do not have it directly, In addition to that it would also include the great point in favor of being able to play from away from home.
