Yeelight V2 color bulb led YLDP03YL not recognized by Alexa

Hi, guys!

I’ve two V2 color bulb led, but only one is not recognized by Alexa. I’m on the Frankfurt server, although I did use Singapore server as well, but none of them seems to do the trick and discover both bulbs.

I’ve reset the bulb that is not recognized several times, but still nothing. It used to work right after I bought it almost 6 months ago.

With IFTTT I can control both, but for home automation purposes, I would prefer to have them working with Alexa.

Any ideas why this might happen and how can I fix.

Your suggestions will be highly appreciated.

Thank you!
