In reply to Ron Walker:
Right, now I see the problem. So there are 2 issues for them, the Apple updates wiping their app's stored data (maps) and having to pull the app from the store due to Apple changing the requirements. Hmm, anyone spotting a theme here?
It would seem fair to assume that they can't tell in advance if any particular iOS update will wipe a particular user's maps before it happens. I've done every iOS update pretty much as soon as they've been released for about 3 years, always had MM on the phone and never lost anything so it seems to be, while maybe not truly random, at least an irregular problem depending on specifics of individual device's installation. But I absolutely agree that the chance that it could happen clearly needs to receive widest possible attention. I would also suggest that it shows Apple to be one of/the negligent party as they are the ones causing the problem making them both incompetent and total arses, but most people already knew that! How can you run a platform like that and get away with it?
The advice on the website of wipe and re-install was meant to have been removed or reworded while the app was not in the store as obviously you can't reinstall if you can't download the app but MM's customer service moves slower than continental drift!
Apple + Memory Map = A perfect storm of idiots?
Shame, I really like MM and my iPhone...
