Is there any way to identify if the QLPreviewController is in markup mode? I have a custom QLPreviewController which is used to preview and edit images in my app. I need to identify when entering the markup mode and make some changes in the navigation bar based on this. But I could not find any variable or delegate methods to identify this. Any help will be appreciated.

We're observing several UI issues with VNDocumentCameraViewController on devices running iOS 26. These screens were functioning correctly in earlier iOS versions. Issue 1 - On the edge correction screen, the top bar now appears as a gray strip beneath the status bar, whereas in previous iOS versions, it was positioned at the bottom of the screen. Do we have any workarounds to address this issue? Issue2 - The edit buttons and their labels are not clearly visible, affecting usability. Im using XCode 16.4 to build to iOS26 and the usage is like below: `let scanner = VNDocumentCameraViewController() scanner.delegate = self self.present(scanner, animated: true)`
