I updated to iOS8.3 and know 1password didn't work anymore. Every time I try to sync it'll crash. Both on WLAN and Dropbox. I can click on the Dropbox keychain and then it crashed.
Sent you the report per app.
Unfortunately I bought 1Password for my Mac before icloud, so I can't use them to try if it works there.
1Password Version: 5.4 Beta 19
Extension Version: Not Provided
OS Version: 10.10.3
Sync Type: Dropbox
