iOS iPhone Help

Just got my Plex set up with Infuse. I am on the 1 week trial and it’s working on my Apple TV 4K but on the iPhone app it isnt working. It’s saying I need to pay to subscribe. Am I missing something here? I am hoping to be able to steam over Cellular for my kids when we are out and about.

Okay so I got the original issue fixed. I am now able to watch movies on iOS using cellular. My next question is how do I have the app update my library? I added about 5 more movies and they are not showing on my device. Thanks,
