Tool for detecting and removing duplicates? [Available in 8.10.18]

Several of the people here are in this situation due to some issue occurring on migration from 1Password 7 to 1Password 8. This issue on its own is a failure of a critical part of the migration function and seems unaddressed in the thread. The system quite simply be checking much better than it does to avoid that fate and recover from it.

The fact that manual duplicate clean up is the solution on a database that for many can approach 1k or greater is simply not good enough. If migration issues occur the duplicate search should really be moved up your priority queue.

Lastly I ended up just deleting everything from the account online and then re-importing. This would be my suggestion to anyone who identifies this problem before using the new data base too much.

This issue alone mostly just got me thinking again about bailing on the product all together. After all it's simply database app at it's core function and if it can't be trusted w that what's the use?

In general the migration process didn't feel well designed to me. For example why would the system not remind the user to go ahead and detach the other vault? This upgrade process is not good, keep working on that or just expect additional users in here over time complaining about that (well the one's that bother to give feedback).

For example presently on iOS I have 2 Vaults in iOS 7. This is how the UI is confusing

All Vaults Screen
1. "Vault for Saving" was still set to iCloud... Not updated to save to the online account... So right there if I didn't change that I would have the issue of saving newly created passwords to a vault I am migrating off of.

1. The old vault was still "On" so of course you end up w a confusing set of duplicates that way too

2. The naming structure is just confusing to someone not working for the company.

"Vaults included in all vaults"
You have
[FirstName LastName] ON
Personal ON

On iCloud
Primary ON

Let me ask you do you think that the average non technical user can tell you quickly which vault is which w this kind of naming structure? Or that one is their old vault from 7 vs where they are trying to migrate too?

In short your UI and migration does the user very little favors to be honest to the point its borderline user hostile. What % of users hose their migration 10-20%?

Another issue you have a promotional upsell function where users can get a discounted price - that's fine... But does this disappear after you pay and sign in with an account - no it doesn't. So is there no QA validation of something as simple as 'if user has paid account stop displaying the promotional notice'... Guess not? Seems like a simple nuance but it's not accounted for.
