Adobe Sign integration with AIP

I have a requirement to sign documents that are protected with Azure Information Protection (AIP).

When I try to upload the document that is protected with AIP, I get the following error message

Adobe Sign was unable to process your document(s). This can occur if uploaded documents contain scripts, macros or Visual Basic code. You may wish to inspect your documents for these elements, remove them, and try again.

How can I use Adobe Sign  to sign protected documents?

Does Adobe Sign integration with AIP in the roadmap ?
