I had to reset up syncing because with my ios because somewhere along the way it stopped working. I was able to get it working with dropbox. It appears to be syncing with agilekeychain, but I also see an apps folder with an opvault file. Not sure if opvault was from my previous syncing method and should be deleted to avoid future confusion.
