When we went in Oct and the app was awful... everytime I tried to scan a barcode to find it elsewhere in the parks it always said "barcode doesn't exist make sure you are scanning a barcode in the park." I had to find CMs to hunt down an item for me in a shop because the app would say a certain item couldn't be found in the parks, but turns out the CMs could always find it in the shops. But at the time it only had around 9,000 downloads of the app so it was newer and needed to be worked on. I am glad it seems to be up and running now!! Plan to give it another try next trip.
