I'd like to know whether the social media settings that I allow for my child work equally whether they launch the associated App or log in via the associated web address. For example if I block Instagram during school hours does that also block access to www.instagram.com
Yes, Family zone blocks by domain so when you block say Instagram all domains associated with Instagram will be blocked, so it does not matter if they have gone through web browser or app Instagram will be constantly blocked

Unfortunately, it won't block the IP address, but in most cases just blocking the domains that it is using is adequate.
