@TeamYouTube the mobile app is having a problem. You can't view many videos in the sub box section. Fix it so people can view slightly older videos from the people they subbed to.
I'm pretty sure it got fixed but I'll tell you what happened. On all devices the YouTube sub box only showed about 15 videos from the normal format of newest on the top and oldest on the bottom. That's all I have though. Good luck with the bug fixes!
