Can't find/access purchased movies/shows on https://tv.apple.com/

Normally I can look at my purchased content library on the Apple TV app, but when I login to the website through my computer browser to try and watch something it's nowhere to be found. The Library just seems missing entirely on the website. I can't even search for the missing content, none of the movies or shows I purchased show up.

I contacted Apple support and chatted with someone who said I should be able to watch my purchased content online through a browser, but that I needed to pay for a subscription to Apple TV to do so. They say I don't need to have an active subscription to watch movies I've purchased if I watch through the app, but that I do need an active subscription to watch through a browser. Which sounds absurd.

Does this Apple support person actually know what they're talking about, has this actually worked for someone else? They mostly seemed confused the majority of the time I was talking to them.
