Attention Warlords! We have received notice from Apple that “starting from July 2018, all iOS app upgrades submitted to App Store must be built with the iOS 11 SDK“. It means if you have a device with iOS 10 or older version, you can no longer download any new updates of Storm of Wars starting from July, 2018. You may still be able to play the existing version of Storm of Wars on your device, but it is up to Apple to decide how longer it will last.
To know for sure whether iOS 11 is compatible with your device, please go to Apple’s website to confirm.

You can also refer to below link from Apple to upgrade your device to iOS11.

Storm of Wars supports iOS, Android and Windows platforms. If you run into this issue, please try to upgrade your device to iOS 11 or download the game on a different platform (iPhone or iPad or any Windows 10 PC or tablets).
Our apologizes for any inconvenience it might have caused. Thanks for your understanding!
