Whilst debugging, I normally kill the APP manually - so I completely missed this new occurrence in iOS 11.. Within just a few seconds of being moved into the background, for example when the user clicks the Home Button - the APP is now being killed by iOS. We've set background execution: NativeApplication.nativeApplication.executeInBackground = true; We are implementing the obligatory deactivate listener which calls: this.stage.quality = StageQuality.LOW; Starling.current.stop(true); In the app.xml we have: <key>UIBackgroundModes</key> <array> <string>remote-notification</string> <string>fetch</string> </array> <key>UIRequiresPersistentWiFi</key> <array> string>YES</string> </array> iOS 10.3.3 and earlier this is not happening.. Odd thing is, I'm not seeing any Crash Logs being written? In the Console just before the APP is terminated I'm seeing the following - it appears to move into the background - and then exits voluntarily? Any help much appreciated.
