is the game broken on ios because its almost impossible to join a server with friends
Sadly iOS is behind on version due to not supporting beta testing.
Android and Steam have beta options so they are all on **v2020.9.1**, while iOS is lagging behind on **v2020.8.31o**. There really isn't much that can be done other than just waiting for the 9.1 version to be an public official release to all platforms. Just hang on tight. :)
