Problem about Apple tv+ Free trial 1 year

I just started my 1-year free trial on apple tv and then realize that i can only watch all the contents on apple tv+ for about 1-2 first episodes that “free” . So i asked my friend who doesn’t have 1 year free trial and she can watch the same contents as me without being followed any subscriptions.

Then i talk with apple support. They told me that some content (which means every contents) need a subscription that pay with their own money. which mean that i can’t watch them with my 1 year free trial. So i asked her how can i do to watch all the episodes on appletv+ and she just told me that maybe i can wait til my 1 year free trial expire and start my new subscription with my own money or cancel it and pay it now😂.

then what’s the meaning of 1year free trial when i can access the contents on appletv+ same as one who dont have any trial😂😂
