Everything was working for months, but after importing a few hundred notes from evernote into the desktop app, it appears that the iOS app stopped syncing (using Dropbox). I removed/reinstalled the app and restarted the initial sync, but it stopped at the same number of notes. Now it just hangs with the message:
x Cancel synchronisation
My assumption is that I had an attachment larger than the current size limit, but I have no idea how to see what resources might be causing the hang. Any tips?
