Keep getting an internal error with reference to the left wheel. I reset to factory settings and re-updated the firmware back to the latest (01.19.98) but still getting the error. I cleaned the wheel to make sure it didn't have any debris. It will run for 15-20 minutes then has the internal error. In the app, it lists the error as follows, "Internal Error - Malfunction due to an internal error. Reset the robot. Error: 106 Left wheel open circuit."
