I was playing with my friend on multiplayer. It was working perfectly until we updated our Minecraft for the new bug fixes. Sense then we have been unable to join each others worlds and most of the time we don't even pop up in the multiplayer section as active when we actually are sometimes when one of us just got off the game and completely closed the app it all the sudden showed us as active. We both restarted our WiFi and phones but nothing worked. We would always get the unable to join the world screen or something like that. The next day it was still broken and the next then this Wednesday my friend came over so we were on the same WiFi and it still didn't work my brother who was on the Nintendo switch tried to join and he couldn't either. We tried different worlds but that didn't work. Thankfully the servers were still working so we ended up playing on the Hive.
