I've been reading online about Sony A7IV focusing issues lately. Front and miss focusing issues.

I have used my A7IV and 135mm 1.8 GM couple of days now and have been shooting outdoors mainly running dogs but also stationary subjects. It seems that bird EYE AF works pretty flawlessly. With dogs and humans eye AF tends to front focus a lot. Focus frame display on camera and on computer shows that it should be on the eye but focused area is on the eye lashes or to somewhere else instead of the eye IRIS like it was on A7III. 

Coming from A7III world that never happened to me but with A7IV I can't trust how it (EYE AF) works. 

I mainly use AF-C but I have tried with multiple different focus area modes.
