Currently the rider app is only supported on stable versions of iOS and Android - we do not support private or public beta versions.
This means if you're using a beta version of iOS or Android the app will not work correctly, or may not work at all. If you're currently using a beta version of iOS or Android please downgrade to the latest stable version of the operating system. You can learn how to downgrade your version of iOS here, or Android here.
Alternatively, you can use any other Apple or Android device running a stable operating system version by downloading the rider app from the App Store or Google Play.
