For months now i haven't been able to get in to my friends worlds, even if all have updated our minecrafts. They've been able to come in to my worlds so we played those. Today they cant come there anymore. It always says "unable to connect to the world" from their world and mine. I have been playing with both android and (microsoft 10) computer, my friend plays with ps4. It used to work perfectly fine but now it's not working.
