Users unable to move camera up and down on mobile

When users play my game, they are unable to move their camera up and down while playing on mobile. However the camera works perfectly fine on pc. I’m not sure how to fix this issue. Any thoughts? Here is a link to the game.

This is affecting me too when I play any game. When my phone is dirty, this happens, and if it happens, I leave and join another server.

Sorry if this is unrelated but I hate that sometimes my camera gets broken/stuck and to fix it is just to rejoin or ride a VehicleSeat that moves your camera. It’s annoying, to be honest.
