Canon cannot be taken seriously in mirrorless without all new sensor tech (for them that is). The whole myriad of issues with the EOS R stem from the not-designed-for-mirrorless sensor from the 5D4 being used in the first place. Read speed is king in mirrorless, a new Sony class sensor would transform the EOS R series in AF, eye-AF, video, DR, VF lag etc. If they can deliver then I may just stand by them for a lot longer to come. I want to like the EOS R, they have some basics right, nice size, weight and ergonomics but this is almost Rebel class in most ways.
