My Thunderbird client fails password verification logging in to yahoo's IMAP server. Last downloaded email was 16:03 17 July, 2017. More current emails are present on Yahoo's server. Password has been changed and re-entered multiple times today. Yahoo is currently set to allow "insecure" apps to access it. Tried Yahoo's 2-step verification with app-specific password (not sure if I phrased or capitalized "mozilla thunderbird" correctly).
