Device app not downloading

We have successfully submitted our device app, drivers and metadata.  Now, when we plug in the camera, I expect that the drivers and device app will be download and installed.  But only the driver is downloaded and installed.  I do not see anything in the DeviceMetadataStore or DeviceMetadataCache either.

Is it necessary to do something special before general win8 release in order to get this to work?

Problem solved:

- There was a MS problem involving sysdev and the metadata submission; MS has now fixed this issue.

- Also, you must add the following registry key (until full win8 release):

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Test Drivers - use at own risk

- If you have > 5 trusted PCs, then the device app download/install will not work; you must remove excess trusted PCs

- Make sure you're logged into the app store and the PC you're using is listed in your account as a trusted PC.
