I love LastPass for a long time and it's my only personal password management tool. Please revert back to old UI which was more handy and less rigid. Though your Web Vault UI is messed up from the beginning which doesn't load in a usable manner on any mobile browser and hard to search.
In the past, the chrome extension UI was so helpful and right now it's a nightmare to update, fill, add anything so easily in the vault from the Extension Popup. This was very nice earlier. Please bring back the old one. Don't kill that experience which was less time consuming to manage things from.
