Can anyone help me, I have 5 Philips hue lightbulbs. They were all working perfectly with Alexa until recently. I don’t have a hue Bridge I turn them on and off via Alexa or the hue app. Now they aren’t responding. I’ve deleted them, added them back. I’ve updated them but still nothing. They work with the app but not Alexa.

Tried that still nothing. It’s so frustrating
Same thing happened to me a few months ago never got it fixed so just use hue app now
Annoying isn’t it. I’m doing the same
