A support pattern we see a lot: someone is signed in on replypilot.app, but the extension in the toolbar acts signed out. Those are two related steps, and one can work while the other needs attention.
The fix is usually to sign in and reconnect the extension in the same browser profile where it's installed. A second Chrome profile counts as a different place.
Two things never to do while sorting this out: send support a password, sign-in link or cookie, or buy a second paid account to get around an access problem. More in managing your ReplyPilot account.
