1st - I bought this game for my son and I to play (me PC, he android), since we don't live together, and after creating everything necessary to be able to login, we add as friends, we can see the other server, but we can't enter a world that the other created. I tried several things on the internet and I don't know what to do.I bought it to play with him, since I saw that it was possible due to cross play.
 
2nd - IN-GAME, there is no notification of new recipe, new item or achievement, only in the notification bar of the computer in the xbox, and this ends up not being seen, as the game is in full screen.
I know that in the java edition it came by default, but I would like to know if I can make the notifications appear, it helps a lot.

Thank's a lot.
