Does Crave have parental controls?
Yes, Crave has parental controls that allow you to require a PIN when viewing content rated above a particular level. You can find this in “Settings,” under “Parental Controls.” The PIN can be changed at any time, with a valid email address. The Parental Controls setting will be applicable for your account across devices and platforms that Crave is available on except Apple TV and set-top boxes.
Parental Controls for Apple TV Gen 3 are to be set up at the device level for all applications. Parental Controls set up via the Crave website or other apps will not apply on the Apple TV Gen 3. https://support.apple.com/en-ca/HT200198
Please note that any parental controls settings on your TV provided through your service provider will not apply to the Crave apps or website.
