You will need to link your Noggin Prime Channel subscription to a Noggin account.

 This can be done on the newly installed Noggin mobile app.

On the Welcome screen, tap Sign In. Under Already subscribed to Noggin Amazon Prime Channel or Apple TV Channel? Tap on Connect Amazon Subscription. On the next screen, you can create a new Noggin account or select Sign In at the bottom of the screen if you already have a Noggin account not linked to a subscription. Tap on Connect My Subscription

Once you’re signed in to amazon.com, tap Agree and Connect to Amazon. Check your email and look for an email from Noggin. Tap the verification link to activate your account. Once these steps are completed, you can sign into the Noggin app on any supported device.

 Alternatively, you can register your account at https://www.noggin.com/amazon. Scroll down and select the blue Connect My Subscription button. Create a Noggin account or Sign In to an existing account that doesn’t have an active subscription. Once you are signed in, tap Agree and Connect to Amazon. You will be sent to the Amazon website to enter your Amazon Prime account information and verify the Noggin channel subscription. Once these steps are completed, you can sign into the Noggin app on any supported device.

Please note, that a Noggin App subscription does not give access to the Noggin Channel on the Amazon Prime Video app.
