Ring Motion doesn’t work

My Ring door bell no longer detects motion at all. I have all motion settings on and set to the highest level and have tried with smart motion on and off, I have activity zone set and enabled it for all events. Firmware is up to date, devices has been hard reset nothing works if the door bell button has been pushed I will get notifications and I can view the live feed but when I check events no motion events are detected even when I’ve stood there jumping up and down directly in front of the camera. It shows all events but motion is always empty. Anyone come across this? My guess is that the motion sensor is faulty.
