Sometimes you can find a trick to make it work, but generally, you shouldn’t expect a subscription bought via some platform (Roku, Fire, Apple etc.) to work outside that platform. If you want to make subscriptions work cross-platform, it’s better to make the subscription directly via the content provider’s website, then sign in to the subscription on various platforms. Make sure you sign in and don’t sign up, which will give you two subscriptions.
Banned but back. Because why not?
