title: Google play test purchase not working anymore
body: <p>I've got an app long time live on Google Play. </p>
  
  <p>My app has two live versions: </p>
  
  <p>3.18 - production</p>
  
  <p>3.19 - beta</p>
  
  <p>I've waited a day after uploading beta apk to make sure it's ready to go. Then, on my test device, I used opt-link for testers to "Become a tester", which went smoothly. Strangely after installing it from Google Play I checked the version and it's 3.18 so production, not beta. But several minutes later I received an update to 3.19 (so it's beta). App works, I can see price of in-app product, but when I want to buy it it looks like it's a real purchase, because there's not "testing purchase" information anymore.</p>
  
  <p>And I don't want to pay for my own products. </p>
  
  <p>Tested on 2 different test devices, with 2 different accounts and 2 different credit cards.</p>
  
  <p>Is there something new I have to add to my code? I've read that recently google changed something with in-app purchase testing, but as far as I know it's just that you can't see test purchases in merchant account.</p>
