If you have purchased GroundSchool Audio for one of our apps and now have installed the app on another device or re-installed the app on the same device, please follow the steps below to restore your audio purchase without "paying again."
Please note that this only applies if your 'new' device is the same basic type as the 'old' device on which you had previously purchased the audio as an add-on for.
The following shows how to restore audio purchased on a new iOS (iPhone/iPad) device. The process for other platforms is similar. The key is that you should look for a "RESTORE PURCHASES" link or button in or near the audio page.
