Free subscription to Apple TV on Roku requires FYC code

Verify that you didn’t inadvertently get the ‘Apple TV+ Screeners’ app instead of the ‘Apple TV’ app.

If so, then get the latter instead.

Hello Jevancor,

Thanks for reaching out to us in Apple Support Communities about your Apple TV subscription asking for a FYC code. We're happy to help by looking into this more! 

Here's a resource that can help: https://fyc.appletvplus.com/faq

This appears to be a promo for voting members, where did you get this promo for your 3 months free subscription?

Let us know and we can continue to help.

Best Regards.
