I cannot bind left click and right click in the settings. Left click and righ click do the same thing. The scroll wheel does not work. I have to click  and drag to look around. The mouse just acts like my finger and is useless. Just try and use a mouse on any mobile device and the problems will be clear. I have seen many people complain about this on the Minecraft forums, the Minecraft feedback website, and Reddit (r/mcpe). Thank you for considering fixing this.
