Whenever I try to sign in the game keeps giving a message to try again as well as Error PlatformNotSupported. I even reinstalled the game but I keep getting the error message. And because I can't sign in I'm unable to change chat settings so I can't join friends' private sessions. Any possible answer out there?
The itch.io version of the game isn't supported. You can use the download page to get a Steam key, if Steam is an acceptable alternative for you. If not, you can refund the game and play the free mobile version, or repurchase on Epic. not that Epic is any good, but at this stage, even that's better than Steam for some people.
