Hello. about a week ago, I installed this game via sidequest. It was not on sidequest at the time. However, I cannot seem to uninstall it even after using sidequest uninstall. It no long shows up via sidequest or sidequest app launcher but my Quest still has "com.oculus.unitySample" that launches your game.
I'm sorry I have no idea how to uninstall sideloaded apks - have you tried deleting the folder through explorer? If you still can't figure it out get back to me and I'll try and I'll help as much as I can.
