IDK if it's just the winter months but my rear camera is pretty useless again as well. It worked amazing with MCU1, went bad with my MCU2 upgrade in summer 2020, service came out November 2020 and replaced the camera to no effect, then a firmware update earlier this year definitely helped. But at some point it seems to have regressed to be barely useful again.
Either that or I am just getting old.
