Common Issues & Quick Fixes
Problem: The PDF doesn’t open for contacts.
Possible causes: The URL is not public, the PDF requires authentication, or the link was mistyped.
Fix: Open the link in an incognito/private browser window to confirm it’s public, then re-check the URL and try again.
Problem: The attachment doesn’t appear in the message.
Possible causes: The attachment wasn’t saved, or the wrong attachment type was selected.
Fix: Reopen the Send Message action, confirm PDF Document URL is selected, and click OK to save.
Problem: The PDF opens in some channels but not others.
Cause: Channel or device limitations can affect how attachments are displayed or opened.
Fix: Test across your target channels/devices and add clear instructions in the message (for example, “Tap the link to open the document”).
