Download this app if you want nothing to work. The web version has the ability to link to your Instagram account which the app doesnt have. You are thus forced to link social media accounts or sign in with your email. The app realizes you have another account and asks to merge the 2, you then receive the spinning circle of death. The app never signs you in and you are forced to kill it. Good luck getting a response from the customer service on the app, I have waiting on a reply to fix the merged accounts issue for over 3 months or simply adding IG to sign in. The scan reader also a bust. It wont work even after using the suggestions on the website. My advice, use the web version to add your drink codes because Coke should have tested the app before released, obliviously they did not.
