Is Paramount+ included in Apple TV+ ? Why does it want to charge me?

No. Paramount+ is its own streaming service. Apple TV+ shows are denoted as such (with the Apple TV+ logo). NCIS is not an Apple TV+ show. You are likely accessing the current season through your cable provider or other streaming service.

Not sure what you mean by the "package" that you purchased. If you've subscribed to any of those services, you'll have access to whatever content they stream. If NCIS LA is only available for the current season, it's best to contact the streaming service directly (Paramount+). According to just watch, only one season is available to stream on Paramount+ (https://www.justwatch.com/us/tv-show/ncis-los-angeles).

Got it. AppleOne doesn’t include paramount+, that’s a separate subscription. ( Apple One - Apple) but I get what you mean. It’s likely that Psramount+ doesn’t have the streaming rights from NCIS or the service is waiting to add content in the future.
