Issues downloading the game, or a particular update could be due to a few different reasons. The first one is a bad/unstable internet connection, which we provide steps to resolve here. The second is a potential issue related to Apple's App Store distribution of the game/update, which we will cover in this article.
During certain times, it might take a while longer for your app store to recognize our latest update. In these cases, you might have trouble downloading the game entirely, or only the latest update version. To fix it you can attempt to force its retrieval by following the instructions below:
1) Navigate to the App Store
2) Tap on Updates (on the lower right hand corner)
3) Locate Sniper3D
4) Tap on Update
If you have already followed the instructions above and you still see yourself unable to update the app, then the issue could be a bad/unstable connection. In this case, please follow the steps outlined in this article.
