On the latest version of the Apple TV Twitch app, the main carousel currently only shows a limited number of live streamers, but gives no indication if there are other streamers currently live. You have to navigate to a different tab to see all live streams from streamers you currently follow.

Either show all live streamers in the main carousel or indicate that you are not showing all currently live streams and offer a link to see all live streams for streamers I follow.

Better yet, provide a multi-row grid, so I don't have to scroll far to the left or right because I happen to follow a lot of streamers.
