Perfect Swing

I am getting a guest account notice when I sign in what the heck is that about?

It also mentioned uninstall 

Hi Larry! I understand that the guest account message concerns you. This issue happens when there is no active Google or Game Center account on your device. I suggest re-logging into your Google or Game Center account and then reinstalling the game. After performing these troubleshooting steps, kindly go to your in-game profile and tap the Link Account button. I hope this helps. If the issue persists, kindly send a ticket. Thank you!
