PDF not locking after signing with Fill & Sign on iPad

Question

I have used Acrobat DC to build a form with multiple pages with the intention of completing and signing it using Fill & Sign on an iPad.

The form seems to being operating fine and I have multiple pages with some of them requiring signatures from two separate people and a couple requiring signature from one of these people.

Upon signing using Fill & Sign I have tried sharing the form back to myself via email expecting the form to be locked but when I open it up using Acrobat Reader on a Laptop the form fields are still editable.

I have have also tried saving a copy on the iPad and this also allows the fields to be edited.

When I use Fill & Sign on the laptop and click the next button I can then share it via email to myself and the form is locked so not sure why the same is happening on the iPad.

Can anyone offer any advice as to why this might be happening?

Thanks

Are you saying that when the PDF is opened in the iPad with the Acrobat Reader mobile it doesn't respect the security of this file after it was signed?

From what you're describing it sounds more like the shared PDF is no longer the original file ; almost like if it goes through a postscripting or flattening process. Can you confirm if that is the issue?

Or are you saying that exactly the same file sent (not a copy that you created) opens fine in one computer with Adobe Areader DC but not in another device with Acrobat Reader mobile app?

You need to verify if when you say "copy " that you're not mistakingly flattening the file or printing as image.

Flattening the PDF file will become just a flat and clean copy of a single printable image layer of what used to be a full PDF; no scripts, no security, no transparency objects.

In any case, before you send out this PDF, you should protect/encrypt the PDF with a password to restrict content editing and such. In addition, save this file using "Save As Other' to also enforce Reader enabled rights.

My main question/ observation is, however, how are you sending out this PDF? As an email attachment or with Adobe Sign directly?
