Bonemeal isn't working with plants at all. When trying to use it to grow a plant faster, it doesn't work, and it also doesn't work when trying to just grow patches of grass/flowers. The green sparkle effect doesn't show up either when tapping things with the bonemeal.

I tried to use bonemeal on all crops, all tree saplings and all growable plants, all with the same result.

This was all done in creative mode on an HTC U11.
