Sorry, I was wrong. We were lucky with the previous submits. Just had another build that was rejected after removing the observers.

@PL_AYGROUND - Can you post the link for that thread in Unity Forum? Thanks

@brightonrich - this is from 2017.3.1p3, my app was approved after yet another try (details on the unity forum, I believe you have been active there as well).

@SORCHA08 and @BEAADS, Open generated XCode project and open "DisplayManager.mm" file and replace -(id)init method.
- (id)init
{
if ((self = [super init]))
{
/*[[NSNotificationCenter defaultCenter] addObserver: self
selector: @selector(screenDidConnect:)
name: UIScreenDidConnectNotification
object: nil
];

[[NSNotificationCenter defaultCenter] addObserver: self
selector: @selector(screenDidDisconnect:)
name: UIScreenDidDisconnectNotification
object: nil
];*/

_displayConnection = [NSMapTable
mapTableWithKeyOptions: NSPointerFunctionsStrongMemory | NSPointerFunctionsObjectPointerPersonality
valueOptions: NSPointerFunctionsStrongMemory | NSPointerFunctionsObjectPointerPersonality
];

for (UIScreen* screen in[UIScreen screens])
[self registerScreen: screen];

_mainDisplay = self[[UIScreen mainScreen]];
}
return self;
}

@BRIGHTONRICH I tried submitting to apple with different versions and all of them were rejected. The last one I tried was 2017.3.1p4 (rejected as well). I would like to try removing the observer from -init. Can you explain to me how I do that? I am using XCode 9.2. Thanks
