Xfi Pause feature is useless

The Xfi pause feature is useless, I had already set up a schedule for devices to disable their access to the internet yet the devices are still able to access the internet, just ran a test earlier but it seems the only way to pause the devices is the "forget" the devices and reconnect them then the pause feature  "Until I Unpause" seems to be the only option to stop the devices' access to the internet the other 3 option doesn't even seem to pause the devices, had to wait like a full min before the devices lose access to the internet, plz fix this, it is really getting on my nerves that I can't do a scheduled pause on the devices, hoping that it will have no access to the internet.
