“Debug data” is technical information about the modules in your car and their current and/or supported settings. Here’s how to send us such data: on iOS, open the slide-out menu from the left of the main screen in Carista and pick "Debug menu" -> “Collect debug data”. On Android, open the slide-out menu and tap on the version label at the bottom of it five times in a row; pick “Collect debug data” from the new menu that shows up. On both platforms, the process of collecting debug data takes about 5-15min. When it’s done, you’ll be prompted to send it in a report; please follow the on-screen instructions to send it. If you’re using a WiFi adapter, you may have to disconnect from the adapter before you send it, in order to have Internet connectivity. Thanks for helping out by sending us debug data!
