Tamron 70-200 and CDAF

I have always used PDAF with this lens and it has been very reliable. I just picked up a mirrorless camera and so started using CDAF. I was not able to achieve proper focus at all with this lens irrespective of amount of lighting condition. BTW, this is the only lens that I have problem with CDAF.

Has anyone encountered similar problem with this lens and CDAF?
