Google has just released a $20 million refund to users who bought cards on its Play store that were sent back to them after their payments had been made.
The company did not provide a reason for the refund, but it is not unusual for customers to receive a refund from Google Play after a card has been lost or stolen.
Google is also investigating the incident, according to a report in the Wall Street Journal.
The move comes a week after the company announced that it had fixed problems with its payment system that caused some users to get refunds for unused credit card purchases.
Google’s Play store is an online app store where consumers can buy apps and other content.
Google has not yet publicly announced how it plans to fix those issues.
