UPDATE: The issue has been fixed by Apple. Please read below for the latest update and instruction.

The new version of Darkroom 2.2 was officially approved by Apple on 8th April. However after several hours of the release, we received floods of support queries. Users reported that they could not update their copy. When the user tries to update the application through iTunes and sync it to iPhone, iTunes returns an error message, “The application “Darkroom” was not installed on the iPhone because it could not be verified.”

We took immediate action to make sure this is not the binary problem that we submitted, and it should not be the case. First, the testing indicates that we do not have any problems on the Darkroom Premium, which was approved several days before the regular version. Both Darkroom Premium and Darkroom were generated from the same codebase (with different features activated). Plus the binaries were signed properly, otherwise iTunes Connect would not have accepted them. Second, this error occurs before the runtime, when verifying the application binary from iTunes store.
