We are running into the same issue, just like OP it happens specifically on the Android app.
There have been some old threads that also reference this behaviour.
e.g: Pan (touchmove) not working in mobile extension
I have tried a super bare-bones demo, where I use the browser’s pointermove event to log out the X coordinates of the pointer-device. It stops after I move my finger roughly 10px horizontally (vertically is fine). This is like 4 lines of code, no libraries were involved
