I just updated my 1Password for iOS (my iPhone) to the latest version (4.5.3).
I noticed that my passwords had not been synced recently. I went to initiate the dropbox sync within 1Password, and I get a screen with the message from dropbox "Error (500) Something went wrong. Don't worry,...". I click on 'Cancel' at the top of the screen, but it just goes back one screen to where it says "Sync with Dropbox - One moment please..." then quickly takes me back to the dropbox error screen. I had to forcequit the app. If I go to Safari on my iPhone, I can load and log in to the dropbox.com website without a problem. If I try to sync with my laptop using WiFi, it syncs fine.
I tried deleting the 1Password app data on the phone. When that didn't work (I still got the same error when trying to sync with dropbox) I tried deleting the app and redownloading it from the app store. Still getting the sync error.
I'm using iOS 7.1.1
How can I get dropbox to sync?
