I ordered a new HS110 from an online seller on Lazada Philippines but I'm having problems making it work.

HS110 won't turn off via Kasa app or physical power button.

I tried multiple factory resets, changing sockets, plugging in a different device. But still the same.

I read here in the forum that I'm supposed to hear a "click", however, I don't hear one when using the app or physical power button. 

Although, when I do a factory reset, or when I plug the HS110 into a socket, I hear one loud click. Probably only when the device first boots up.The attached device turns ON after that click, but cannot be turned Off anymore after.
