I can’t get Amazon Echo to discover Yeelight strip scenes

New to Yeelight, set up app and strip successfully yesterday. I have changed to Singapore server and Alexa changes colour, brightness etc by voice. I would like to ask her to use the pre-set scenes, but it won’t seem to find them when I use the discover scenes from within the Alexa app…could anyone assist please?

Please try with scene bundle, which can be discovery by Alexa.

Excellent… Many thanks
