Ring Wired Cam - Light not triggering unless stood underneath it

HiWe have had our ring set up for approx 5 years now, one of the devices is the Wired Ring Camera and up until about 6 months ago it worked fine, at night the light would trigger at night whenever motion was detected. We have found that whilst it still picks up motion fine the light will only come on if you are virtually stood underneath it. We have double checked all the settings, rebooted numerous times, cut the power but nothing has worked.Any suggestions on what we can check next?Thanks
