I downloaded the app. It worked perfectly for 3 days. I had all the features I use on a daily basis such as text, podcast and google maps. All suddenly, it stopped working for no apparent reason. I changed the brand new USB cable provided with the car, unstalled the app and install it again, looked for updates and more.I went to dealership to ask to have it repaired on my new Elantra Preferred 2020. Nothing seems to work. Please provide a solution. I am very disappointed with your app.
