If you are appearing as Registered in the app, this means that you are not signed in as a Premium subscriber. The account you are signed in under is a free account, not a paid account. There are one of two reasons for this:
1) You do not currently have a Premium subscription, because you have not paid for one. To sign up for a Premium subscription, click the green Learn More button on your Account page.
2) You have already paid for a Premium subscription, but you are appearing as Registered. This means you are signed in with the wrong email address. Sign out and sign back in again, making sure to sign in with the email address associated with your Premium subscription.
