uidocumentinteractioncontroller

问题 the project I have uses UIDocumentInteractionController to copy/share and image to Instagram, it worked fine for a while. As soon as I selected the instagram app from the iOS share sheet. the image was open in the select filter section. Recently, the image is now opened in a view with an x to close and two buttons, one to select stories and another one to select feed, if I select feed, then the camera roll is opened and the last picture is selected or the camera but the image I was sharing

问题 I use the UIDocumentInteractionController to preview files of different types within the app. This has worked fine in the past, but when running the app on a device with iOS 13 the document is not presented. What is shown is the file name and type. I have looked for similar questions and found this UIDocumentInteractionController showing file name and file type , not file contents I've tried NSUrl.CreateFileUrl(FilePath, null) as the comments on that question suggest but this doesn't solve
