Now, in 27 of December in 2021, there isn't any solution to this problem. On the app in settings it has a mouse and keyboard option to play it. But when I connect the mouse and the keyboard it doesn't work. I can't walk. There are other games that has a great implementation of the mouse and keyboard. Why Minecraft supporters aren-t solving this problem? It will be great if there are this implementation.
I'm waiting for the answer
With the 1.19.10 Keyboard an Mouse support work perfectly
