Documents on cloud not loading on all devices

I always save my documents for school on my adobe cloud so I can access them on all my devices, but for some reason I’m able to pull up all documents on my computer, but not my iPad. I three documents giving me trouble which already have notes and highlights, so I prefer not to delete and redownload in an effort not to loose document info. I’ve saved my edits to the document cloud, but still aren’t showing up despite signing out and back in.
I expect to have the document load as usual, but I simply get a blank screen.
