Hi @NeilG2 Thank you for that and this will be very helpful for any future users who experience this problem.
That`s good. Its best to keep any additions to a minimum, so that the parental controls are not compromised.
There is a danger that adding CDNs (Content Delivery Networks), may allow unwanted content to bypass the controls.
Those BBC ones should not really be blocked by parental controls anyway, so they are ones which should be added by the parental control team so they are allowed.
If a user really wants to block BBC content, they can add it to their blocked list, which should take priority over all other settings.
