How to get notifications whenever mobile screen orientation changes?

Hello,

I have a widget that should change its layout based on a current mobile screen orientation. I can use GetDeviceOrientation but I do not want to check it every second or so…I have found that there is a node called ‘Application Received Screen Orientation Changed Notification Delegate’ which I hoped I can use for my purpose. The Target pin of this node demands PlatformGameInstance which I do not know how to get. I even tried casting GameInstance to PlatformGameInstance but it didn’t work.

I may be on a wrong track…Can you help me, please, to be able to get notifications via blueprints every time screen orientation changed?

Thank you in advance!
