I am using a UIDocumentInteractionController to preview small PDF files (approx 83K). I noticed on iOS10 when calling presentPreviewAnimated that the preview takes a very long time to load the document (5+ seconds). While loading, a blank white screen is displayed.
Then, when clicking Done, there is another pause of ~5s where the app becomes completely unresponsive (can't scroll or tap done again), followed by the dismissal of the preview. Has anyone else noticed this issue? If so, have you found any way to resolve it?
