@TeamYouTube On http://m.youtube.com/TV and http://youtube.com/tv the list of subscriptions for a logged in user is almost empty and only contains videos from today. Consistent error on all devices. Can you acknowledge this issue? App is fine though.
http://YouTube.com/TV , log in, go To subscription tab. I see only a dozen videos, the oldest has been posted 22 hours ago. Nothing beyond that. List just ends. Consistent on all devices. Android apps and http://youtube.com (no "/tv") show the correct list though.
