IAP in App Store

[J. Landman Gay]

I'm confused about how the purchase flow works so my question is probably incorrect. There is 
no error when I see the "complete" status, it only shows up in my logging file. After adding 
additional logging, it looks like "complete" is sent after every transaction. But if something 
goes wrong, like asking for a product that isn't in the Play Store yet, there are no status 
reports except "complete." The app doesn't receive any other info and Android doesn't display 
any dialog. Seems like I should get an "invalid sku" status error.

Here's part of the log where I made a successful test purchase (product ID obscured):

***
Wed, 6 Oct 2021 14:12:55 -0500 BEGIN IAP PURCHASE: <PRODUCT ID>
   -- purchaseStateUpdate logs this:
Wed, 6 Oct 2021 14:13:15 -0500 Purchase state: <PRODUCT ID> paymentReceived | PurchaseID: 3

   -- fullfillment handler logs this and sends info to back end server:
Wed, 6 Oct 2021 14:13:15 -0500 Purchase complete: true | <PRODUCT ID> | paymentReceived
Wed, 6 Oct 2021 14:13:15 -0500 queryServer about to query for newPurchase
Wed, 6 Oct 2021 14:13:15 -0500 newPurchase params: {"packageid": "<PRODUCT 
ID>","transaction_id": "3","source": "android"}

   -- and finally purchaseStateUpdate returns "complete":
Wed, 6 Oct 2021 14:13:15 -0500 Purchase state: <PRODUCT ID> complete | PurchaseID: 3
***

I'm working in the internal test track and the choices in the test purchase dialog do not 
include a Cancel button. To cancel, I tap outside the dialog and it goes away. Sometimes I get 
an email about my "purchase" (which is normal) and usually it verifies a cancellation. But one 
email had some additional test info:

"This test purchase was cancelled because it was not acknowledged. You should ensure all 
purchases are acknowledged so they are not subject to refunds. For more information see 
https://developer.android.com/google/play/billing/integrate#process."

I just repeated the same cancellation method just now and did not get that warning in email. I 
didn't actually get an email at all.

One faintly amusing thing is that Google is counting my unpaid test purchases as real ones in 
their Play Points history, and yesterday I acquired enough points to rent a free movie and 
advance to level Silver for additional benefits. :)

Given how complex their IAP store setup is, I think that's only fair.
