Verifying non-consumable purchases

[mtilhan]

Hello,

I'm integrating for Google Play. When making a purchase request, if it is a consumable product, it is necessary to perform a "Consume" operation. This works fine with the "removePurchaseFromQueue" function. However, for non-consumable products, "Acknowledge" operation is required instead of "Consume" operation.

According to Google official documentation, it is necessary to call the "BillingClient.acknowledgePurchase()" function for this operation.

When I look at the project code, I can't see it anywhere. For this reason, my non-consumable product purchases are always cancelled. Again, according to the document, it is normal for this to be cancelled;

"Note: If you do not acknowledge a purchase within three days, the user automatically receives a refund, and Google Play revokes the purchase."

As a result, can you arrange to sell non-consumable products?
If I am doing something wrong, I would appreciate it if you could write.

Thanks a lot.
