Bug Android test purchases fail: "Google BillingResponseCode = BillingUnavailable"

Hi,

We're experiencing an issue with IAP. Details:

• Description of your issue
  • I am trying to make a test purchase in our mobile game on Android. But it fails all the time in my device and two of our colleague's device. But it works on one of our colleagues.
  • The last configuration that I've tested was Unity 2021.3.28 + IAP 4.9.4.
  • It was working on our last build (Unity 2021.3.11 + IAP 4.8.0) but it fails now on this setup as well.
    
  • Another note: I can't make IAP on our other game anymore.
• Steps to reproduce
  • Start a purchase of a product
  • See the failed log
• Your purchasing script
  • Purchasing script is the same with last working production release.
• Device logs

• Unity Version
  • 2021.3.28 / 2021.3.30 / 2021.3.27 / 2021.3.11
• Unity IAP version
  • 4.9.4 / 4.9.0 / 4.8.0
• Platform you are building for
  • Android
• Store you are targeting
  • Android Play Store

So what could be the reason?

 

Any updates? I'm having the same problem.

 

I didn't get the reason yet, but it works when I use VPN.

 

I had the same problem on production build also. I can't pay with my real card.

 

In my case, the purchase doesn't even work with a VPN.

 

We have same issue.

Unity LTS 2021.3.31f1
In App Purchasing 4.9.4

We have updated to respond to Google Billing Library 5, but the tests continue to fail.

Failed Message : - Google BillingResponseCode = BillingUnavailable
Failed Reason : PurchasingUnavailable

If you find a solution to your problem, please let us know.

 

Same issue,

Unity LTS 2021.3.14f1
IAP 4.8.0/4.9.4

Failed Message : - Google BillingResponseCode = BillingUnavailable
Failed Reason : PurchasingUnavailable

 

Same here,

We have also same issue with a game that's published 5 months ago. So I guess the problem is server side, not related with Unity or IAP versions..

 

Unity LTS 2021.3.31f1
In App Purchasing 4.10.0

We have updated to respond to Google Billing Library 5, but the tests continue to fail.

Failed Message : - Google BillingResponseCode = BillingUnavailable
Failed Reason : PurchasingUnavailable

---------------------------------------------------------------

We have updated 4.9.4 to 4.10.0 but still have same problem.

But we found one weird solution.

If you have multiple Google accounts on your device, delete all but one and the test will run normally.
