Developer responseposted 9 months agoPlease, make sure you are logged in to your Duolingo account before trying to put your username in Duolingo Boost popup. The extension doesn't ask for your credentials, it just uses your existing Duolingo session. When you are not logged in, Duolingo Boost is not able to fetch your account data.
