Apollo add-on on XP mobile: force re-buy after purchase

Question

I've recently purchased the Apollo add-on on XP mobile. When I tried to access it today, I got the screen saying that Apollo is not free, and offering me (again) the option to buy it for $4.99. What do I need to do to help the app realize it's already been purchased?

Answer 1

Check that you're using the same ID that you used to originally purchase it. Otherwise try completely quitting the app and restarting, and perhaps sign out and back into your store ID.
