The AF is not broken.Canon finally makes a smaller cinema camera and the AF is broken.
It just requires a lot of light.
People are comparing it to R5, R6, A7S III, FX3, and FX6.
Those cameras use eye detect instead of just face detect.
Eyes require far less light to detect.
If Canon is going to make the camera look like a DSLR then they should add eye detect if they can because that is what many people expect when they see it.
