You have to click the flag a couple of times for the animation to sync and work. COPPA, I think, is a set of laws about child online saftey regarding how Google tracks info about children. Now they made a new set of rules about how YouTube creators have to be careful on what they make videos on. If they make child friendly content, they don't get ads on their videos (meaning no money) and subscribers won't get notified when their favorite YouTube creators upload, and it is rated 13 and over, you WILL get ads on your videos, and people WILL get notified. But if your video is incorrectly labeled (for example, children watch your video if it is rated 13 and over), you will get a fine of $42,530! I don't make money off YouTube, but I think that's a little intense. And no, I'm not really getting sued. :)
