We are facing an issue with VNDocumentCameraViewController where the tick button in the top-right corner becomes completely unresponsive after a document is scanned. When the user taps the tick button immediately after capturing the document — before the "Ready for next Scan" text appears on screen — the button freezes and the documentCameraViewController(_:didFinishWith:) delegate is never called. Through debugging, we observed that if the tick is tapped before the scanned image thumbnail appears in the bottom-left corner, the delegate is never triggered. However, if the user waits for the thumbnail to appear and then taps the tick, it works as expected. This indicates that VNDocumentCameraViewController has an internal processing pipeline that must complete before the tick button becomes truly interactive, but there is no visual indication or API callback to inform the user or the developer when it is safe to tap. We would appreciate Apple looking into this and either disabling the button during processing, queuing the tap, or providing a delegate callback for when the controller is truly ready.
