yes, I think the app already uninstalled as I can't see it in any page, even using search, it not exist in my iPad. I tried both development or distribution key but same result.
When I change the package name, it can work again. or I install it on my iphone, work too..
seems the problem only on my ipad device but I'm really don't know what happened!
what I'm doing before this issue is add iAD in my apps, modify some code , some testing and submitted to itunesconnect. (switch few times for development/dustribution key ) After this I keep doing some enhancement and suddenly got this issue
