I have a total of 4 Kasa light switches in my kitchen. I've set up a group (named kitchen) for these light switches. One of my Kasa light switches randomly doesn't respond about 50-60% of the time when I tell Alexa to "turn on kitchen lights." It will also randomly do this in the Kasa app when I turn on the kitchen group, not just when I use Alexa. If I turn it on manually (by hand) or by telling Alexa to turn on/off that specific switch, it turns off and on 100% of the time. 

I have:

1) restarted the switch

2) pulled the light switch from the wall and ensured my wiring was correct and no wires are touching where they shouldn't be

3) restarted all my switches in the kitchen

Nothing has fixed it so far. Any other suggestions or has anyone else experienced this?

Thanks
