I'm using the android app on an Nvidia Shield.
Since last week my mouse wheel is extremely slow. I had to increase from 3 lines at a time to 100 lines at a time to get it close to what it was before when scrolling through a browser window.
In one of my main games, Elder Scrolls, it now does nothing. When redoing the settings in game it would recognize that I am moving the wheel but still does nothing when actually playing.
Edit: when using shadow through my own PC everything works just fine.
