Skill works in voiceflow and adc but not in echo dot

I can test my skill in voice flow and in adc it works fine there but I am facing an issue while doing it with my echo dot. I’ve used same amazon accounts on both the platforms. I can even see the skills in **Your skills ** section in the alexa app on my phone.

Alexa’s response when I call my skill- “ sorry I didn’t find a device named xyz “
