What you were expecting to happen, and what actually happened?
Gems is currently bugging me to download an update, except there is none available.
I can return to the game and access all normal features, but for about 5-10 seconds. Then the update message comes up again and I have to cycle back to the App Store.
Do you have any screenshots or video you want to share with us so we can see the problem? Attach them to your post!
I just checked, the problem is on Steam as well and Steam updates automatically. The game actually loads fine if you don’t push the quit button, but you can’t do anything until you press it and then it shuts down.
