I upgraded my iPhone6 to iOS11.0.2 and 1Password has gotten very difficult. When I go into search, the sync indicator keeps spinning and the app freezes. I can get to the Settings screen and the Syncing icon is spinning. There too, when I click on anything, it freezes. Of note, I upgraded some (but not all) vaults to opvaults two weeks ago.
1Password Version: 6.9
Extension Version: 4.6.11
OS Version: iOS11, Mac High Sierra
Sync Type: Dropbox
