Hi - I updated brave about a week ago on my Macs (Ventura) and the password popups have stopped showing up for websites that I have saved passwords for. Right clicking password fields lets me open all passwords in settings and they’re definitely all there and if I show + copy a password I can get into the site, but it’s a bit frustrating.
I waited to see if the next update fixes it, I installed the latest over the weekend and it’s still a problem on both my Macs.
