Play Billing Lab

This app is garbage. There's no help file. There's nothing intuitive in this app to figure out how to use it. There's nothing to tell you how to get your app to show up in the Billing Lab app. Whoever developed this didn't even bother testing it on devices with on-screen navigation buttons, for the Continue button is underneath the navigation buttons. Google should be embarrassed to put something of this low quality out to app developers. The support email address does not even work. Garbage!

Very often is not update prices according to selected country in configuration settings, or with long delay

Thank you, I found this tool very useful in terms of different currencies testing. The app saved hours and hours of my life:)
