App doesn’t always work. – Smart Lights, Wi-Fi Review

I just installed a Legrand wall switch. It works mechanically. The app turns the switch on and off but it never provides an indication that it is on. When turned on the icon in the app switches momentarily to white and then back to black even though the switch is still on. I tried the Alexa skill and it will turn the switch on. But it would will not turn off with an off command. But it will turn off if I issue a second On command. And the indicator in the Alexa app always shows that it’s on. I have several other Tplink switches that work fine. This one is going back.
