Thank you for the followup reply.
Troubleshooting Corrupt Purchases:
A. Reinstall this:
Delete the game, and then re-download it.
B. Contact the Developer:
If need be, contact the Developer of the game, asking them for assistance. Perhaps this is a known bug, and they have a fix for it. You'll find their Contact Us information in the app's site of the App Store.
C. Request a New Purchase:
Sometimes, when you purchase something, you may lose the internet connection (i.e due to utility work down the street) rerunning in the file becoming corrupt. So, contact Apple, requesting a new file.
Apple Contact Info:
Why the Wait:
Phone calls are taking a bit to go through at the moment, due to lots of calls. With the Coronavirus Pandemic, many are at home at the moment, with much time on their hands to contact Apple. So, just stay on the line, and you will get through :)
