I finally bit the bullet and bought 1Password4 for iOS, even though the 1Password3 app still works fine.
I'm having trouble with Settings|Sync|Dropbox.
I'm a long time 1Password user and have been syncing all this time via Dropbox. No issues so far. Standard setup: a 1Password.agilekeychain directory in the Dropbox dir.
Currently, under Sync, I have:
iCloud ON and successful (not sure what iCloud sync is, why it's on and why I need it, if I switch if OFF I still have the Dropbox problem)
Dropbox ON with a "Problem with sync. Tap to fix" message.
File Sharing OFF (not sure what that is why I need it)
If I tap on Dropbox, I get a long wait and a progress bar, then the same error.
Can you please advise how to proceed?
