Adobe tag attachment

Hi,

We are using adobe e-sign and are using the attachment tag to allow people to upload documents.

If the first reviewer uploads a document, the second reviewer can see these attachments at the end of the pdf as expected. If the second reviewer adds attachment, they are not visable on the final document, nor are the first attachments. 

Am I missing something or do I need to add some more tags?

Thx,

Pim
