I have just tried using the google play plugin, I do have a problem however.
On my Android phone, my game loads up and asks me to login to google, I enter the username and password, it then displays the list of things to agree to.
When I click on agree, A black message box is displayed which says
The server refused the connection. (http://Some really long link)
I wonder whether you have any ideas about what is going wrong here? (It has been built using Crosswalk)
