I followed https://developers.google.com/actions/dialogflow/first-app tutorial and built my first google action. The action is working fine on my laptop browser in the test (Followed "Preview the App" section of the tutorial) environment. However, when I am trying to use this action on my phone by saying "OK Google talk to my first app". It's not working. Is it supposed to work on my phone as well? I have logged in with the same Gmail account on my phone also.
PS - I have posted the same question on "actions on google" google plus community google as well but I am not sure if that community is to post such questions or not. Therefore, I am posting it here also.
Thanks in advance!
