Hi Bill, apologies I’ve been away from my desk for a few days. Everything looks good to me so I am curious why you are still having signing difficulties. As I mentioned earlier (or may have mentioned) for simple testing on the simulator or your own device the signing that LC does (using your provisioning profile) should be sufficient. For wider distribution you would need the additional steps Matthias's life saving app provides. Either way, please do let us know what the outcome of your efforts are as I’m sure all of us can learn something from the experience.
