Alexa Skill doesn´t find Lamp

Hi support team,

my Yeelight Crystal Lamp isn´t working in connection with the Alexa Skill anymore.
Stopped the service a few days ago. I disabled the Yeelight skill and reconnected it, but the Alexa app doesn´t find the lamp. I can see and control the lamp with the Yeelight app on iOS without any problem.

Anything I can do? Or should there be a software fix for the Alexa Skill?

Would be great to hear from You.

Best regards
