You need to be in the extension environment to launch sites. Click the puzzle piece icon in the Edge toolbar and see if the LastPass icon is there. If the icon is missing, download it from the LastPass website: https://lastpass.com/download
Also make sure the icon is red, and you are actually using the extension. If it says https in the toolbar, then you are not in the extension. Click the red LastPass icon in the Edge toolbar. If the LastPass icon remains hidden. click the puzzle piece icon, right click on LastPass and pin it to the toolbar.
I do same thing but my favorite nyt daily puzzles not download working.
