Those who remember my previous questions, I am trying to set up a sync between Dropbox and any pdf annotating app that will enable me to annotate pdfs on iPad and later to sync with Dropbox. Good Reader can do it (first download pdfs in the app, annotate them and upload back to Dropbox). Now the question is, I am trying to delete a trial sync that I set up, to confirm that it indeed works. I am unable to delete it, instead I get following messages. In first message, it suggests me to delete synchronization record under 'web downloads' but there is no such record under web downloads. Any idea how to work with this? Bonus question, The annotations made in Good Reader are visible on laptop but adobe reader that opens pdfs by default in iPad Dropbox app doesn't show any annotations. Any way to fix this? Thanks in advance.
