  <p>I set items in the In-app products and published them</p>
  
  <p>I signed the app and uploaded the signed app to Google play and to the device via adb.
  -- same error
  I tried to publish the app and then download it to the device
  -- same error</p>
  
  <p>The error pops after I press "Accept &amp; Buy"</p>
  
  <p>My thought is that it could have something to do with my Google merchant account, any Ideas?</p>
  
  <p>Thanks,</p>
