"Thank you guys so much for your hard work! Overall feedback was very positive especially given such a short timeframe to enable these events in a production environment and get the apps approved in App and Play Store. They said the app was very responsive especially with the scanning and UI looks good. We do have more work to do, but it was definitely a successful MLP1 launch!"
