As per the title, when I activate the PIN unlock, set the PIN and subsequently lock the vault; I can go to a webpage where a login exist in the vault and press the shortcut keys Ctrl+Shift+L and the user/password is autofilled. Again, all this while the vault is supposedly Locked.
This behaviour does not happen when PIN unlock is unticked and vault is locked
This might be a related issue to the one posted in here: (1) and here (2). So it seems that while the PIN unlock is selected, the vault is not really locked.
Edit: using version 1.39.1 of the Chrome plugin
