Thanks for letting us know. Just to confirm, are your subs reporting that no notifications are sending or that your videos aren't showing up in their subs feed? Appreciate the details!
If you think your videos were age-restricted in error, you can appeal in Video Manager. More info can be found here: http://goo.gl/xrSJJ7 . Also, some computers and networks in public institutions (like school wifi) have Restricted Mode enabled by the administrator.
