If you are having trouble with the scanner...
Try lining the code up with the red line rather than center it in the box. I submitted 5 codes, and once I figured out how to line it up, all my codes were accepted the first time.
Kind of disappointed that Rewards and Grow On need to be opened in Safari, but I will keep the app just for the convenience of being able to scan the codes; they were a huge pain to type in, especially since I always have a handful of them to submit at one time.
