Hello, so this issue has been happening for quite awhile now and even with steady wifi I'm not really sure where the problem lies. I play on mobile with an iPhone 10, there's no glitches expect the problem of not being allowed to join worlds. With my brother, we use the same exact wifi network but is still unavailable to join each other's worlds. After a month or so of not playing the game, everything suddenly went back to normal and I was allowed to join different worlds. But after a few days the problem rose yet again. I was wondering if I could get some help on this issue and get back to playing more regularly together with friends, if this could be helped in any way or form that would mean a lot!
