############################################################################################I exactly followed the steps illustrated in documentation :
https://developers.google.com/actions/assistant/updates
The issues encountered are :
ISSUE 1 :
app.askForUpdatePermission(INTENT) : is not updating the permission to send push notification for the intent but it says the permission is granted. and in case tried to execute the 'final_permission' intent again, its say the permission is granted .
As when I try to execute app.isPermissionGranted() , it returned false.
ISSUE 2 : The Server 'https://actions.googleapis.com/v2/conversations:send' returned 500 or 400 Error randomly.
I am using free plan of FireBase (Spark) Is it because of that ?
