If you redeem a Magpie Pro offer code in the App Store, open Plan and billing in the iPhone app and tap Restore purchases. Pro is added to the Magpie account you are signed in to. Before, a subscription bought outside the app could not be linked to any account.
The app checks your store subscription when it opens, at most once every six hours. It no longer shows a message each time. For example, if your store account's subscription belongs to a different Magpie account, the app says so when you tap Restore purchases, not every time it opens.
A Google Play purchase that was cancelled before payment no longer shows as pending.
