[Question] UIDocumentPickerViewController "Preparing file..."

[wyattbeavers]

We have debug & release schemes for our app. When adding files from a UIDocumentPickerViewController in debug, the "Preparing file..." alert takes 30+ seconds to complete, typically ending with an error that the selected file cannot be found. Comparatively, when building for release the alert completes after only a second or so, and the same file selections are added to our app successfully.

Can anyone explain what might be causing the difference in behavior between the two schemes? The main change between them is that debug uses a separate Bundle Identifier. Is there a config value in the Intune property list settings for the document picker that is specific to the bundle id? I thought it might be a Queried URL Scheme value, but none of them appear to govern the document picker, at least at a glance.

Additionally, is it expected that the SDK modifies the document picker with this alert even for unenrolled users?

Thanks for any help.

Hi do you have a minimal sample with repro steps, I can download and test in simulator?
