are we just f((ked if we play on itch? unsupported platform. theres no way to change birthday, cant make an account, and we got charged more than every other app that supports the game...
the only thing that worked for me was making a steam account using the 'claim steam key' when you click the download Among Us at the top of the screen. You have to link the purchased game from itch.io to Steam in order for the game to run with an account. Use the 'Game' tab on Steam and 'Activate a Product on Steam' to download the game. You should be able to launch the game on Steam and make an account.
