I just bought and installed two of these KL430 LED strips and they work fine.  The app works to control them as expected.  I connected my Kasa account to google home, which was successful.  I can see the two devices in the google home app and their status.  The problem is that I can't turn them on or off using the app or by voice.  No errors or feedback.  Google home shows the light toggle, and the voice command gives the success feedback chime.  It just doesn't work.  When I refresh the status in the app, it will update to the actual state again.  What is extra weird is that I CAN control brightness in both the Home app and via voice.  What's going on here?  Both strips updated to the latest firmware when I installed them yesterday.
