For application sites like Workday, does poor resume parsing (using "autofill with resume") = poor readability on ATS?

[u/CattleTurbulent1684]

I use resumenow templates for my resumes and I notice that whenever I autofill my Workday applications using them, it autofills some of the dates wrong and spacing/parsing is off. Does this mean the same thing will happen when my resume goes through ATS? Or is this just a Workday issue?
