I am having the same trouble as evG686 also on an iPhone 8. After opening the App, the screen is black and after few seconds the App closes automatically. I tried turning my phone off and on. I tried signing out of GameCenter and signing back in. I paid the $10 for no ads a couple weeks ago. Now it doesn't work. Please advise with a fix for this.
You're right -- that works. I put in a ticket about this, and they emailed tonight that they put out a new version update. So we'll see how that goes. Thanks for the tip, evG686.
