How can I restrict kids from downloading free channels like YouTube?
The help articles suggest that adding a Roku Pin will require you to enter a pin to download any channel. I've done that and set "Making purchases and adding content" to "Always require a PIN to make purchases and add items from the Channel Store." But you can still download any free channel you want.
Even Roku support said "Unfortunately, yes" you can't stop kids from downloading free channels like YouTube. I find that unbelievable that there is no way to stop my 6 year old from downloading YouTube and watching videos of the scary clown from IT eat Georgie.
