Interesting. In a Studio Session, you can only upload PDF’s, but I haven’t tried attaching a different format as you did. I would assume because you’re not checking out or checking in like a Studio Project it wouldn’t save. I’m kind of surprised the attachment even stayed attached. In most situations, I teach students to use Projects for everything and only send documents to a Session if multiple people absolutely have to work at the same time. Even then I only send individual sheets, not a whole set.

I don’t think this helps you, but this is a place to chat through ideas. Thanks for posting @ChrisRiley
