Hit or miss experience
It works reasonably well (still not the best, but I can accept that) on iOS and Android, but it didn't help on macOS. I cannot use some of the desktop apps (for example, Roblox Studio) unless I uninstall it completely (disabling rules won't help). I did not receive much support from Qustodio after reporting as well. In the end, I had to uninstall Qustodio. I may terminate the subscription (expensive for the quality of service) if it is not resolved this week.
