I've had a look at your account and it seems like your trial has ended so you're currently not being filtered. You'll be able to resubscribe by going to your subscription page and checking out the $5.95 subscription.
If Netflix and YouTube is blocked during Play and Sleep time, then it should not be working. Could it also be a possibility that the content may have been downloaded or preloaded before the session started?
It would be worthwhile having a look at the routine to ensure it reflects the controls you have in place.
I haven't heard of this happening before, can I please get you to give us a call, or schedule a call back via this website https://www.familyzone.com/au/contactus for the best time when you have the device. I would like to go through this and see if we can replicate it.
