We have created an interactive PDF form that requires a Digital Signature that we would like to have available on our website for users to fill out. Unfortunately, the one signature form field disappears when viewed through a web browser (chrome) after we uploaded the form to our website. All other form fields are available, but the signature field is not visible nor clickable.
If the PDF form is downloaded and opened in Acrobat on a computer the signature field is available, but if done on mobile through the Acrobat App the form field disappears visually, but if you click where this field should be, the signature button does appear to fill in.
We are looking to have this form perform the same no matter what platform it is viewed on. I'm working in Adobe Acrobat Pro DC for Mac and finding support for this specific issue has been quite difficult. Any help to resolve this issue would be appreciated. Thank you.
Not all browsers support this.
I understand that, but that still does not explain why it is not working correctly on mobile in the Acrobat App or even which browsers DO support this feature. We normally recommend downloading the form, but with this issue on mobile, this recommendation is no longer a valid solution as most of our audience will be accessing this form via mobile.
Acrobat Reader on Android or iOS doesn't supports Digital Signatures.
"but that still does not explain why it is not working correctly on mobile in the Acrobat App"
Adobe never added that to the mobile app. No, it isn't a good thing.
"or even which browsers DO support this feature."
So far as I know, no browser makers bothered to support signing. IE, until it is discontinued, uses Adobe's plug-in and might allow signing.
Unfortunately, your expectations, while reasonable, cannot be fulfilled. You must explain in detail how your customers can download, must use Mac or Windows, must use Adobe software, etc.
