iOS: AppStore installs old version and then offer to update to the new one

Question

I submitted a new version of my app to AppStore and it was approved a week ago.

However, I delete the app from the iPad, install it from AppStore and I get the old version installed. The "Install" button on AppStore turns to "Update" instead of "Launch" and then I get the new version installed.

Does anyone know what could be happen here? Why the new version is not installed in first place?

I tried with iOS 5 and iOS 6

Answer 1

TestFlight or a Ad-Hoc network is almost always the cause of this problem.

Also, when you back up via iCloud and sync back your apps they will not automatically update.

Revoke your app from Ad-Hoc and from TestFlight. It should update to the latest version.
