First, I typically have to login twice. Type username, type password, accept the login on the MFA app, enter PIN on the MFA app. Then the extension login screen refreshes and I have to do it all again: type username, type password, accept the login on the MFA app, enter PIN on the MFA app. Pretty annoying.
Second, when I create a U/P on a site, the extension offers to save it, then often doesn't. Sometimes, I click the button to save the password, and nothing happens. Other times the button is just grayed out. This happens about half the time in general and almost every time when using my personal email address that is linked to my business account. So what do I have to do instead? Copy the password when I create it (half the time it doesn't even copy, which is another annoyance), click on the extension, click on Vault, log in (even though I'm already logged in), accept the login on the MFA app, enter PIN on the MFA app, click to add new password, paste the password into the appropriate field, and finally curse because the whole process took too long and the copied password is gone from my clipboard, and now I have to go through the site's password reset protocol to log in.
