Hi,
it looks that Android app for youtube is not controlled time management control if it is currently used and time management should start prevent use of device.
In my case I have setup time management control so that use time of tablet will end at 7pm, but if kids are watching videos via this app and clock hit to 7 pm (and time control should prevent using of tablet) they can continue to watch videos until they close app and try to restart it.
Any solution how to get it working?
