For some reason, 1PW on my iPhone quit syncing with Dropbox.
I tried troubleshooting by disconnecting the Dropbox connection and syncing over Wifi with my Mac standalone version (5.3.1). No connection was made between 1PW iOS and 1PW Desktop. I believe I can still sync my Mac Desktop version with Dropbox, but I'm using a trial version here so I cannot / don't update this data as often.
I assume there's some version compatibility issue, but that doesn't make complete sense since it was working not long ago.
I've been a 1PW user since 2010 or so, and prefer to own the standalone versions instead of the monthly versions of 1PW.
My specs are as follows:
MacBook Pro running MacOS 10.11.6
1PW Desktop 5.3.1 (Trial)
iPhone 6 running iOS 11.4
1PW iOS 6.1.2 (Paid Pro)
BTW: Dropbox is not paused, but may have been at one time.
1Password Version: iOS 6.1.2
Extension Version: Not Provided
OS Version: iOS 11.4
Sync Type: Dropbox
