Minecraft pe beta?

I just downloaded the beta version of mc because I couldn't control the mouse (which is connected to the mobile phone) properly.

but now i noticed that you can't play multiplayer.

I left the beta program and now it says I should download the public version but it still says beta

Did you uninstall the beta version too?

The problem with mouse control under Minecraft Bedrock is always the problem that is not supported properly under Android. So I would either play with a touchscreen or with a controller.
