Can only turn on bulb using the switch?

Hi, I intend to plug the Yeelight into the switch. I expect it to turn on when I switch on the physical switch. However, I see from online reviews that I can only turn on the bulb using the bulb. Is this true?

I mean “turn on the bulb when using the APP”:

This is ridiculous … If a bulb can’t be turned on by wall switch, it can’t call a bulb… We just provide some options that can make it behave per user’s settings.
