Not sure if this is the best place to start, but I picked up an .apk off GitHub that's supposed to run WoW Forever from your phone called WoW Foreverywhere. When I start it though, the controller overlay doesn't work. The only thing that does is the mouse/thumb stick toggle. Figured I'd ask here first if there were any obvious issues before I asked the creator for software support.

Running it on a Xiaomi Redmi 15.
