No buttons appear on the screen.

The menu button does not appear in Minecraft's BedrockEdition, version 1.16.20.

I want to use Makecode, so I'm using the version 1.16.20 that connects to Makecode without any problems, so I can't upgrade to 1.16.210.

I would like to ask you to fix the bug so that the button will appear in 1.16.20.
