I regularly have to block and unblock kids from the internet.  I have one device, a laptop, that I blocked from wifi and now neither the tplink app nor the laptop can see each other.  I then plugged the laptop in and used it via ethernet for a day.  At night I blocked the wired laptop and put it away.  In the morning, I went to unblock it and I can't see the it on the blocked device list, so I can't unblock it.  I checked the mac address and there is no indication in the tplink blocked list.

Any ideas would be appreciated.
