HELP

I have cellular enabled! I am able to join other worlds if I'm remembering it started about when the bee update game out it was so annoying I couldn't invite anymore I could show off my projects or any thing I had to rebuild them in friends worlds! This is issue makes me want to scream please help! Also I've noticed that multiplayer is on when I join the world but when I check settings when I load the world they are off I leave and check again then their on then I join then their off don't dare say privacy it is not gonna magicaly change from public to strict (this is not two different issues the multiplayer auto turn off causes the invite button to go missing)
