I've upgraded to the Pro version for $4.99 on my personal iPad2 and it works great, however my iTouch is requesting the I pay for the Pro version again. I tried the Restore option from the iTouch and entered my iTunes password, but it says I need to purchase the Pro version again. None of my other paid IOS apps work this way (unless there is no iTouch version). I paid for other apps and they are alway available on my other devices without the need to purchase them again. I've paid anywhere from $0.99 to $19.99 for apps and never had to purchase them a second time, so I'm assuming this is a bug.
What is supposed to happen here? If I need to purchase Pro again, then what happens when I retire my iPad2 and purchase an iPad Air? Do I need to re-purchase Pro each time? If that is your intent, don't you think this should be made more clear to your customers?
