[The application report shows that YouTube has been used for a longer duration than the permitted time]

The device usage is set to a daily limit of 1.5 hours then block device, why is YouTube able to be used for 2.5 hours?

 

[Google system app can still not be blocked on Android devices]

The AppLock work-around solution is just a joke, any third party locking app without device admin can be easily uninstalled. 

KSK appears completely powerless under the impact of the Google App bug/limitation, reduced to being useless.

Rooting the device may be the last option, but it comes with significant risks.

If the problem cannot be resolved, I will definitely not renew the subscription after it expires.
