IOS 12 required?! – App Store Connect Review

Why does this application require you have iOS 12 on your device? I have an older iPhone 5 I use for beta testing and it's highest iOS is 10.3.3 I've beta tested on newer iPhones however my iPhone 5 finds many bugs that newer iPhones don't have and has saved me many times. Please make this app work on iOS 10+.
