No "Watch Next" on web, but shows it on mobile

When I watch remotely, is there a reason why there is no "Watch Next" via a browser but the button shows up on my iPhone app and AppleTV app?

There are many inconsistencies in the web admin and the clients.

While the web admin can browse and stream, we do not currently consider its experience that of another client. We consider it more of an advanced administrative tool. So you’ll see lots of things different in it.
