I was hesitant to update my Dogfight App because of some flaws I'd heard about, but…again I made another costly decision. I regrettably decided to anyway. Now, all my time and money is wasted because after I did update, my app locked up on me. UNPACKING.…was the word I saw for 2 days straight whilst I patiently waited. I may end up deleting this app for good. C'mon, really? Is this one of those sneaky ways of making money off of us? I give this app one more day to replace the expensive aircraft I so patiently waited to buy or it's gone. I'm sure that everyone would feel like I do if that had happened to them.
