Describe the bug

Donations being refunded after 3 days (10% refunds lately)
Refund not initiated by me and not by the user (received an email why he got a refund)

Expected behavior

Acknowledge all purchases within three days. Perhaps a library update?

Additional context

Wrote an email to Google about donations being refunded automatically after 3 days.
Got the following reply:

Hi,

Thanks for your patience.

If you use the Google Play Billing Library version 2.0 or newer, you must acknowledge all purchases within three days. Failure to properly acknowledge purchases results in those purchases being refunded.

Google Play supports purchasing products from inside of your app (in-app) or outside of your app (out-of-app). In order for Google Play to ensure a consistent purchase experience regardless of where the user purchases your product, you must acknowledge all purchases that have a "Success" state received through the Google Play Billing Library as soon as possible after granting entitlement to the user. If you do not acknowledge a purchase within three days, the user automatically receives a refund, and Google Play revokes the purchase. For pending transactions, the three-day window does not apply when the purchase is in a "Pending" state. Instead, it starts when the purchase has moved to the "Success" state.

Here are some specific resources on the Android Developers site:
