Blue Light on Car Cam not flashing?

Hi according to RING the Blue LED on the top is supposed to flash every 8 seconds to show they system is active and everything is working. Mine will flash every 45 seconds if the inside cover is opened. If closed Ill get a blue flash every 2:15 min ... Does anyone top LED flash every 8 seconds like its supposed to do or do I have a dud ? Per Ring - **Blue Pulsing Light** Ring Car Cam's main LED will quickly flash blue two times every 8 seconds. This indicates that Ring Car Cam's sensors are monitoring your car. To restart the device, press the setup button (on top) for 7-10 seconds
