I have a new I2. Rear LEDs stopped working completely. When first turned it on, I get a center rear LED that flashes two short purple flashes twice and then stops. Nothing else. Front LEDs work normally after motors are armed. No messages in the App and everything functions normally otherwise. Only other issue that happens but I don’t think is related is the Cendence occasionally shown in its display, “RC Reset” and has audible alarm. If I reboot the the Cendence, it appears normal. Appreciate any help.
