Hi,
I had installed the private alpha subterfuge through the website and since the game came out through the App Store I now have two icons, one for the alpha and the other for the regular game.
When I try to delete the alpha icon nothing happens. Please help me cuz it is pretty annoying to have a useless icon on my home screen

If you're on Android you could go Apps -> the app in question -> Uninstall.

Not sure how iOS does it
