Google Play Billing 2.0 testing pending transactions and acknowledgement

Question

I'm transitioning to Google Play Billing library v2.0.0 and there are two major flow differences. One is purchase acknowledgment https://developer.android.com/google/play/billing/billing_library_overview#acknowledge and the other is handling pending transactions https://developer.android.com/google/play/billing/billing_library_overview#pending.

For pending transactions the docs state that

In addition to two test credit cards, license testers have access to two test instruments for delayed forms of payment which automatically complete or cancel after a couple of minutes

...but I only have access to two regular test cards, no delayed ones.

And also that:

For purchases made by license testers, the acknowledgement window is shorter. Instead of three days, purchases are refunded and revoked if they are not acknowledged within five minutes.

But I still get 6x 5-minute long renewals for a monthly subscription, so a regular behavior, not the new one.

Of course I called enablePendingPurchases() upon init.

Clearly the new flow is not enabled for me, but why is that?

hi, did you find out what was wrong ? – Barye

I have just revisited and the acknowledgement just started working. If I don't ack the purchase, the subscription page in consumer google play says that I need to reopen app, otherwise the purchase will not complete and on test account it expires after 3 minutes or so. So this is fine. But still no idea how to enable pending purchase testing, I still only have two test cards. – Sheik
