Breaking a block doesn't give you the item

I entered my world for the 5th time today, apart from stuttering and lag when putting or removing a block, now when I break any block it literally drops nothing. I tried to exit and enter the world and the game several times, i even rebooted the phone and the bug persist. I created this world yesterday, I will have to create another world, but at least, I hope you fix this bug ASAP

Here's a video and the world.
