Buggy and Frustrating 🤬 For a paid for app, it's so buggy. Never had these issues when it was free from Anki. Cars randomly disconnect, race types don't always work, can't navigate back from certain screen so you have to kill the app and open it again, single player just sits and waits for a second player, and since the last firmware update the cars mostly just spin around in a circle 🙄 Overall, embarrassingly poor.
