I just started using 1Password 7.3.657 (coming from 1Password 4). While I like the new reused password detection feature, it seems to not work properly in that the item for which the Reused Password banner is displayed still shows that the Reused Password banner even after regenerating the password.
1Password Version: 7.3.657
Extension Version: Not Provided
OS Version: Windows 10
Sync Type: 1Password.com
