Now the app purchased on Google Play can be returned within 2 hours.
Until today, Android users had only 15 minutes to get a refund in case of an ill-considered purchase. After a series of lawsuits, Google has increased the time limit for familiarization with the application. Now the buyer of virtual content will be able to get the money back within 2 hours. To do this, click the “open and refund” button.
Google also made it clear that users will not be able to use an extended period of time to, for example, play paid games, and then delete them, and repeat this several times. The opportunity to return the same purchase will be provided once. After that, the “refund” option will disappear, and the “uninstall” button will appear instead
