Selling ads on an app whose purpose is to help your customers purchase your services is ridiculous to begin with. On top of that, the interfere with the functioning of the app on older phones. Also, Ive missed several buses because the app is not entirely accurate. Update: one more thing that Wmata cant do apparently is maintain an app on 2 different versions of the same operating system! Im still on iOS 9 and the app is useless. It crashes every time I open it.
