If you are unable to access any premium content through your Apple TV after renewing the subscription, here's what you can do:
- Make sure you are signed in your Apple TV Settings with the iTunes ID that renewed the subscription
- After you've verified that the iTunes ID is the correct one, in the Tastemade app go to Settings, and click on the Restore Purchase option. This will check with Apple to see if there's any active subscriptions and apply them.
Additionally, if you need to check your iTunes subscription status, you should be able to do it from iTunes. Apple has a support article on their site showing you how to manage your subscriptions: https://support.apple.com/en-us/HT202039
