I'm on a Amazon Fire Tablet, and when I try to turn on the new features(Experiments: Holiday Creator Features, etc.) I get stuck on the "Generating World" screen. My friend (iOS, iPhone) joins, and can get in the world while I'm stuck on the "Generating World" screen, but it is very laggy for my friend and I still can't get off the screen, I don't know what to do, and I really want to see these new features.
