HI!

I have a OnePlus 3t with Android 7.1.1 and I have a really big issue in Minecraft PE. I have bought on Amazon the Universal Foldable Keyboard from Microsoft and I am currently writing with it, so it works perfectly!
When I want to change the keybindings in Minecraft PE, it won't let me. Don't know why...
I klick on one of the keybindings and when I press a button on the keyboard it doesn't take it!
When I am in a world I can control Steve, so the keyboard does funktion in Minecraft PE. It is a little bit sad that the official Microsoft keyboard won't work with their product (Minecraft PE).
Does anyone have a solution????
