When asking to launch my application to google assistant I get a message about google sharing data preventing to launch the app

I'm trying to deploy my first Dialogflow / actions-on-google App (Pamela Target). I could test it easily until a few weeks but recently I started to get a message with : (translated from french: Service and confidentiality) saying that informations are shared with third the third party app with an 'OK' button to click. see : screenshot .But when I click: everything is blank... it stops, even not starting the app...

I tried on the Google simulator, and it works fine I tried on the Google home mini, and it works fine only on my android device it does this...

I am still hoping to find either what parameter/configuration or what i may have done in the code that could prevent the app to work on the phone
