I've completed making new editable PDF forms for our company that includes the use of digital signatures. These work completley fine through email and we have had no trouble with them in this regard.
The problem is when uploading these forms to our website to replace the old ones so our customers can access them, the digital signature field disappears completely. All other fields are visible. I'm not sure if there is a particular privacy setting on the document which could be the issue? Unless this is something I need to get in touch with our website provider about instead.
I look forward to any helpful responses!

When you say "uploading these forms to our website to replace the old ones" are you referring to users opening this PDF from a web browser?
I would suggest considering the use of Adobe Sign in this type of workflow since you'll get the ability to publish a PDF as an online form (and of course, if this is what you're inquiring about...).
However, Some of these features are not available in the individual plan that is already featured with your current paid subscription of Adobe Acrobat Pro DC, and you may need to upgrade to a team or business plan.
