I also have this problem. I think the problem has to do whit button size. It kinda work on button size 70. (As in it works but if you tab to close to the edge will you stop moving). But anything above button size 71 makes you not move at all.
I'm also experiencing this bug. It has to do something whit button size. It (semi) work on button size 70 but not on anything above button size 71.
I'm experiencing the same. But for me does it even go further. it takes a full minute to load any world, new or old worlds. when leveling up a villager does the game freeze to, same goes for going to the nether. you also start to fall through the world upon going to another dimension.
my question is, is this caused on Minecraft side or on my side of things. and if caused on my side, how do I solve it?
