title: iOS14 missing buttons in "Save to Files" menu
body: <p>I spot that my code behaves differently on iOS13 / iOS14. I am downloading pdf file and showing it with UIDocumentInteractionController</p>
  <pre><code>     DispatchQueue.main.async {
          let controladorDoc = UIDocumentInteractionController(url: PdfUrl)
          controladorDoc.delegate = self
          controladorDoc.presentPreview(animated: true)
      }
  </code></pre>
  <p>after pdf is shown I am clicking &quot;Save&quot; button. Here is the difference:</p>

  <p><a href="https://i.stack.imgur.com/f0SUc.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/f0SUc.png" alt="iOS14" /></a></p>
  <p>Save and Cancel buttons are missing. How to fix that ? I was thinking about overloading buttons in actions menu but I didn't find how to make that.</p>
