Can I schedule internet blocking for certain times of the day?

I am trying to find out if I can utilize Screen Time on current iOS to schedule “Internet Blocking”?? Like I’d like to setup M-F no internet use between school hours, 10a-2:30p and then again block overnight M-F 9:30p- 7a. Weekends I’d let him access parental controlled apps and websites more often during the weekend as he is a teen and stays up later.

Canopy app offers this, however it has never worked. My son can always see Instagram feeds, DMs and phone calls. Other apps work at random. I have spoke with Canopy support numerous times and they still do not know how to block Instagram and many other apps during their Internet Break scheduled time.

Are there any other apps that do this, if I cannot schedule internet breaks with Screen Time.

I don’t want to take his phone or block gps or his ability to phone someone, during those times - just all internet access. (He shares his phones location with me, which I do not want to be blocked from seeing.)

We do tak to our son very open and honestly, however he still gives in as most teenage boys do, so please do not offer parental tips.
