Unable to add Digital Signature

Question

In creating a fillable form on Adobe, I am unable to add a field to have someone digitally sign. The fields I am adding are not a normal textbox. The ones I have tried using that say "add a signature field" only allow the person to type normal text into the box. After watching youtube videos, they have a button on their edditing window that says "add a digital signature".  I do not have that button available to me. I will upload a screen shot of my options within Adobe. What do I need to do from here?

Hello!

I hope you're doing well, and we apologize for the delayed response and the trouble.

Please ensure you have the latest version of Acrobat installed on the machine: 25.001.2043x Optional update, Mar 19, 2025. Check for any pending updates from the Menu > help > check for updates, install the updates, restart the app and the machine, and check. For more information, see this: https://adobe.ly/4iYGMH9.

Verify Document Permissions
- Ensure the PDF isn’t certified or restricted by the author. Go to File > Properties > Security and confirm "Comments, Fill & Sign" is allowed.
- Check Document Security Settings

Verify Form Field Settings:

Ensure that the signature field is designated for digital signatures and not as a standard text field.
To set the correct field type:
- Open your PDF in Acrobat.
- Navigate to Tools > Prepare Form.
- Select the signature field, right-click, and choose Properties.
- Confirm that the field is set to accept digital signatures.
For detailed guidance, refer to Adobe's instructions on using digital signatures.

Flatten the PDF:

Complex PDFs with layers can cause issues.
Open the PDF in Acrobat, go to File > Print, select 'Adobe PDF' as the printer, and click 'Print' to create a flattened version.
This process simplifies the PDF structure, potentially resolving signing issues.

Let us know how it goes.

Thanks,

Anand Sri.
