I sometimes need to use a password in a local app (Windows 11) rather than in my web browser (MS Edge). I am usually able to copy passwords from the browser extension (v4.136.0) by typing the name of the item in the Search your vault box, clicking on the overlapping blue boxes and selecting Copy Password.
Despite being rewarded with a green tick that suggests the password has been copied, the clipboard contents are unchanged, i.e. they still contain whatever text I had previously copied. I have confirmed this by pasting the clipboard into Notepad.
