Worst update ever

Wow, I cant even right now mojang, every single time I log in to mc I cant play the worlds Ive created and every time I make a new one, it crashes, god, this game used to be so good before, but now I cant even play it. Please mojang, fix this, or I want my $6.99 back.
Update: Problem fixed! I just had to wait at the main menu to sign into Xbox live completely, so now I LOVE YOU MOJANG, YOUR THE BEST ?. But seriously, you guys a have gotten minecraft soooo far, and its amazing to watch it develop still to this day, thanks for all you do, and I feel super happy now :D
