I don't know why, but for some reason, there is a bug when using Avast Passwords to log into websites that are using Google's Invisible reCAPTCHA. There will be a message saying "incorrect captcha," but no captcha ever shows up. It's as if the program doesn't read that a password is actually being entered. I've tried this with other password managers such as Dashlane, and they all work fine, it's just Avast Passwords that Google can't detect or something. I don't want to post the url here, but if someone would like to test this I can pm you.
