Hi

I'm replacing an older switch located beside another (old set-up picturedbelow) . I've connected it successfully, it has power, connects to wifi, but just doesnt power the light on or off - manualy or by the app. This switch feeds the second switch in the box. The second switch works so the lines are correct, but cant get the Kasa switch to control the light. Pictures attached of old and new wriring. Any suggestions?
