If a PDF does not open or export

  1. Keep the original document. If page edits have not saved, do not discard them just to retry an export.
  2. When it is safe to leave, reopen the document and check which pages display correctly.
  3. Confirm that the device has free storage.
  4. Try exporting to Save to Files. If this works, check the receiving app separately.
  5. Open the saved copy and verify its page count and appearance.

Large documents can take longer to prepare. Wait for the share sheet rather than repeatedly tapping Export.

If deleting or saving an annotation fails

Do not assume the change was saved. Check the page and keep the source document. Record the message shown, including any error code, and tell support:

  • The device and app version.
  • The page number and annotation type.
  • Whether the problem occurred immediately after adding the annotation or after saving and reopening the editor.
  • Whether it happens every time or only sometimes.

A later successful attempt does not explain an earlier failure. If possible, provide a non-sensitive sample that reproduces the problem.

If annotations look different after export

Check whether you chose merged annotations or editable annotations. Editable annotations may behave differently in other PDF apps. Use a merged export for a finished document, then inspect the exported copy before sharing it.
