Describe the bug: When sharing a file with UIActivityViewController, the message "Preparing file ..." remains displayed. Then wait a few minutes and the file will be shared. The file size of shared files is not large. There was no problem with SDK version 18.2, but this problem has been occurring since version 19.0.

To Reproduce Steps to reproduce the behavior:

  1. Launch Microsoft apps such as OneDrive and Edge.
  2. Show Share Extension and select my app.
  3. The message "Preparing file ..." remains displayed.

Expected behavior: "Preparing file ..." message will disappear immediately and the file will be shared.

@bbdev9805 - Thankyou for sharing the required logs.

You mentioned it is working as expected with versions - 17.6.0 and 18.2.0 whereas the issue is only with versions 19.x . Can you also share the diagnostic logs for a working version to validate our theory of the issue.

Thanks for sending the logs over. In the non-working logs, we saw -

IntuneMAM: Failed to create item provider for file. Unable to encode object: CRWWebView

CRWWebView is a custom WKWebView object within edge which the SDK is failing to encode. However, this does not explain why the sharing prompt of "preparing file" is shown indefinitely. This logic would likely be handled by the sharing app (edge in this case). But the working scenario logs seem to be different. They seem to suggest the file is being shared from the custom app to edge. This would be a different scenario (since the repro steps for non-working logs shows that file is shared via Edge browser share extension) and thus might explain different behavior.

To further investigate, we need an internal repro. Could you please provide the .ipa or code snippet with a repro video recording to show the behaviour on my mail id mentioned above?
