Opimization says attachments need to be optimized separately
I am trying to optimize a pdf but when I click to optimize PDF then Advanced Optimization, I get a message saying "This PDF file contains attachments. PDF Optimizer will not process the attachments. You'll need to open each attachment and run this command to process all files." I have no idea what attachments they are talking about, how to go about finding them, and then once I do, how to process them if they are all within one doc.
