I finally decided to upgrade my MacBook the other month to one with the new Apple M CPUs so I thought I would give the iPad version of PzC a try since the Apple M CPUs are able run iOS apps. I remember playing the iPad version several years ago and thought it was quite decent at the time...
The Apple App Store recognised I was a previous owner of the game so it allowed me to download the game for free and I can install it and start it without any problems. However when I try to run the Grand Campaign it is empty and it asks me to pay for Afrika Korps, Soviet Corps etc.

As far as I remember I used to play the Grand Campaign on iPad previously...? I am 99% certain I did...
Can someone shed some light on this? How do I get the GC to run on iPad?
