Issue with Screen Orientation after clicking on a deeplink

Hello.

I’m using Unity 5.6.3 and I have an issue with Screen Orientation on iOS 11.x after clicking on a deeplink.

My setting on Unity is “Auto Landscape Right, Left” (without portrait, portrait Upside Down).



The problem occurs when I click on a deeplink from another app to go to my app. The app then only shows in the left corner of the screen and shows in a smaller size than the actual resolution. The rest of the screen is black.

Issue:


Normal screen:


This issue occurs with iOS 11.0.3 but not in iOS 10.3.3.

< Current development environment >
* Unity 3D engine: 5.6.3 f1
* Test Device: iPhone 7+ (iOS version: 11.0.3)

Please let me know how to fix this issue. Also when can I expect a modified Unity version?
Thanks.

 

Anyone? It's a serious issue because I can't use any deeplinks for iOS right now...
