When I was Trying to Break Blocks In MC Win 10 Edition, The Animation that plays when you break a block, does not play.
Recreate:
Create New World (Any kinds but flat, and in creative)
Find a Hill (Mountains Work Best)
Go About 4 - 6 Blocks away from the block(s) You want to break
Click / Hold The Break Block Button (I use Left Mouse Click)
75% Chance That The animation Will Not Play
*CONFIRMED FOR MINECRAFT PE 13.1 ON NEXUS 5X RUNNING ANDROID 6.0.1*
