I've followed the instructions here: https://support.1password.com/upgrade-ios/#step-1-back-up-your-1password-3-data
and tried this: https://discussions.agilebits.com/discussion/74964/restore-old-backup-in-newly-installed-1-password
and this: https://discussions.agilebits.com/discussion/comment/320989/#Comment_320989
But the new 1password crashes the moment Import Now is selected. The report should have been sent to you so I'm hoping you have a solution?
