On the Norton Password Manager on my Chrome Browser (both updated), when I click the Fix Issues, it display dozens of websites, most no longer valid. However, I have to physically open each one and click the Delete button to remove the entry. There should be a checkbox column, with a checkbox to select all checkboxes so you can deselect the few you want to retain, so you can selet each record that you wish to delete and have an option at the top to 'Delete All Selected'. This would have saved me well over an hour of work. I'm 'positive' others have encountered this issue.
Well, that is the responsibility of the user, not Norton.
This process may be set up this way for safety reasons. It would be all too easy to select a number of entries and accidentally select a couple by mistake. Once you would click on apply, or delete, it would be too late to save the logins chosen by mistake. Having to do one at a time has less risk of deleting the wrong entry.
Having said that, this might be a good suggestion for the Product Suggestions board https://community.norton.com/forums/product-suggestions
