title: Google in app billing migration from V2 to V3
body: <p>I have an existing app using IAB V2 I would like to update it to V3. I've done some testing and noticed the following:</p>
  
  <p>*When I publish items in the new developer console interface I can buy them with the IAB V3 implementation but with a V2 implementation I get "impossible to buy this item".</p>
  
  <p>*When I publish items in the old developer console interface I can buy them with the IAB V2 implementation but with a V3 implementation I get "impossible to buy this item".</p>
  
  <p>Is it the way it's working or may be I'm doing something wrong, If I want to migrate to version V3 do I have to put items in the new interface only? What about people who have the V2 app, are they going to be able to by items anymore ?</p>
