Fix Submit Button Not Working in Acrobat PDF Form on iPad
Question details
The user is unable to use the Submit button on a distributed Adobe PDF form while viewing it in Acrobat Reader on an iPad.

- Product
- Adobe Acrobat Reader
- Device & OS
- iPadOS
- Scenario
- Filling out and attempting to submit a distributed interactive PDF form on a mobile device.
- Observed behavior
- The submit button fails to execute its action, often resulting in no response or simply opening a blank email draft rather than transmitting the intended tracker data.
Verify that your iPad has an active internet connection and that you are running the most recent version of your PDF reader, as outdated apps may lack support for specific form submission protocols.
Verify and Update Submit Button Actions on Desktop
Mobile PDF readers often have restricted support for complex JavaScript or desktop-only form workflows. Ensure the button uses standard, universally compatible submission settings.
Distributed form tracker workflows designed in desktop Acrobat often rely on proprietary background actions that iOS and iPadOS applications do not support natively.
To resolve this, the form's button properties must be checked and potentially reconfigured on a desktop computer to ensure cross-platform compatibility.
Launch your desktop PDF editing software and open the problematic interactive form.
Enter the form editing mode, right-click on the uncooperative Submit button, and select 'Properties' from the context menu.
Navigate to the 'Actions' tab. Ensure the action type is set to 'Submit a form' rather than a custom script that may not run on mobile devices.
Verify that the submission URL or Mailto link is correctly formatted and uses basic HTML or PDF standard submission types, then save and redistribute the file.

Use Manual Document Sharing as a Workaround
If you are the recipient of a broken form and cannot edit its underlying properties, use your iPad's native sharing capabilities to return the data.
Seamlessly Fill and Share PDF Forms with WPS Office
Avoid mobile compatibility issues by using WPS Office. Its powerful built-in PDF tools allow you to effortlessly fill out interactive forms, save your data securely, and share documents directly from your iPad or desktop.
- 1. Download and Open: Install WPS Office on your iPad and open the interactive PDF form within the app.
- 2. Input Your Data: Tap on the highlighted text fields or checkboxes to quickly fill in your information.
- 3. Share the Completed Form: Tap the Share icon to send the flattened or interactive PDF directly via email or your preferred communication app.

Frequently Asked Questions
Why does the PDF submit button work on my PC but not on my iPad?
Desktop PDF applications support complex scripts and proprietary distributed-form workflows. Mobile apps, including Acrobat Reader for iOS, often lack support for these advanced background processes, causing the button to fail.
Can I edit the submit button's properties directly on my iPad?
No, mobile PDF viewers typically do not feature advanced form-creation tools. You must open the document in a desktop PDF editor to modify action buttons and form properties.
What should I do if my iPad app only creates an email instead of submitting tracker data?
This happens when the app falls back to a basic 'mailto' action because it cannot process the tracker data protocol. As a user, manually emailing the completed form is the best workaround. As a creator, redesign the button to use a standard HTTP POST submission method.
