Youtube Subscriptions on Apple TV

I am subscribed to 30+ channels on youtube. On my computer, I can see a list of all these channels in my subscriptions section. On my Apple TV, however, I noticed that my newer subscriptions don't appear to be showing up, and only 25 user channels are shown in the subscription list. Does Apple TV limit its list to 25 subscriptions? Or is my Apple TV simply not updating its subscription list on a regular basis.
