Dropbox synching has been spotty in the last year or so on the iPad, occasionally I have to delete everything on the iPad and redownload from Dropbox. Often the document loads but links do not come across, just text so I need to delete/redownload to get the page links to work. Now I am getting repeated "Dropbox Session Ended, Do you want to relink?" modal error messages redrawing faster than I can click them. I can delete the app on the iPad and supposedly start over again but it suffers from the same no link issue when I get the document loaded and then the relink error starts again in a loop making it impossible to use the app.
