Hello Donnovan1987,
Thanks for posting in the Apple Support Communities. We're happy to look into this with you.
To make sure we've got it right, you're attempting the direction provided in Connect apps and add your TV provider to the Apple TV app on iPhone - Apple Support to link your streaming apps. Right?
Have you had the opportunity to verify the apps you're attempting to link are supported with this feature? If you haven't that would be the best place to start. Check out Availability of supported apps in the Apple TV app - Apple Support to confirm.
Follow up with us and confirm the actions/steps you're using, streaming service compatibility and if during the process you've received any error messages.
Best regards.
