Can you post a minimal example. Because the following works in MKII 
(counter reset at each chapter)

\setupfootnotes[way=bychapter]

\starttext
\dorecurse{5}
{\chapter{New Chapter}
   \dorecurse{5}{\input ward\footnote{A quote by ward}}}
\stoptext

The following also works with the counter reset at each section:

\setupfootnotes[way=bysection]

\starttext
\dorecurse{5}
{\section{New Chapter}
   \dorecurse{5}{\input ward\footnote{A quote by ward}}}
\stoptext


and the following works with the footnote reset at each page:

\setupfootnotes[way=bypage]

\starttext
\dorecurse{5}
{\section{New Chapter}
   \dorecurse{5}{\input ward\footnote{A quote by ward}}}
\stoptext

All examples were run using:

ConTeXt  ver: 2018.04.04 00:51 MKII  fmt: 2018.7.3  int: english/english

and the documents were compiled using

texexec --xetex filename
