My son is 11 and is always watching YouTube.it has content restrictions on it but there is still lots of silly behaviour on it that he copies. We have a smart tv so I removed the YouTube ap but he was able to access it throug voice command, he also sussed out he could access it through sky as well. It seems to be impossible to block or get rid of. I have timers on his Xbox and his chromebook so I’m able to manage his time on them I just can’t seem to block YouTube! Any ideas? I have pulled the plug on the Internet but sometimes I need to use it for my work.
