Apple will not delete or modify your apps if they are neutered for extra-legal concerns. You have to intentionally delete them or update them to a neutered version, yourself.
But there is no newer version available. Also OP seemed to like it after a fresh install two days ago.
Again, where's the reference?
I think that just the QR Code scanning feature was removed in the newer versions..
Other than that, everything is available on the web page anyway, so it's probably just a limited browser application that pins you to their site, and cleans up the interface a little..
I'd love to know if newer versions allow you to buy something by just pointing your camera at a QR code, and then hitting approve/send..
