Help Needed: Ring and Amazon Echo 4th Generation as Ring hub

I bought the echo 4th generation and ring motion sensors. I have added ring skills on my alexa app. Also, addresses on both the the apps are the same. The Echo firmware is also up to date. However, the ring app cannot find my Echo. Please help.

Hi @user51953. The Echo (4th generation) can be used as a Bridge for Ring Smart Light devices; which Motion Sensors do you have?
