title: Google Play in-app billing v3 getSkuDetails() returns cached results even if IAP's prices were changed
body: <p>Google Play v3 API's IInAppBillingService.getSkuDetails() method returns cached results.</p>
  
  <p>Let's look at this scenario:</p>
  
  <ol>
  <li>I have an item called com.my.item in the Google Play Console with price $1</li>
  <li>I run my game, invoked IInAppBillingService.getSkuDetails(), and indeed I get the $1 price.</li>
  <li>Now I return to the Google Play Console and change the price to $2</li>
  <li>I run my game again, invoke the method from (2) and still get $1.</li>
  </ol>
  
  <p>Observations: </p>
  
  <ol>
  <li>The Google Play purchase activity does show the correct price ($2)</li>
  <li>Waiting for a while (2hours approx) doesn't help.</li>
  <li>Clear Data on the Google Play app resolves the issue.</li>
  <li>We tested on Galaxy Nexus (4.3), Samsung Galaxy S3 (4.1.2), with latest Google Play versions.</li>
  </ol>
  
  <p>Anyone encountered this issue?</p>
  
  <p>Thanks, Max.</p>
