The problem is that the csv file is cached.
And also if you
<filesmatch ".(svg|jpg|jpeg|gif|png|ico|css|js)$">
remove, for example, png from the line, then *.png files are cached anyway.

How to make csv not cached?

Answer 1

<FilesMatch "\.(csv)$">
    <IfModule mod_expires.c>
        ExpiresActive Off
    </IfModule>
    <IfModule mod_headers.c>
        FileETag None
        Header unset ETag
        Header unset Pragma
        Header unset Cache-Control
        Header unset Last-Modified
        Header set Pragma "no-cache"
        Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"
        Header set Expires "Thu, 1 Jan 1970 00:00:00 GMT"
    </IfModule>
</FilesMatch>

if it doesn't help, then before nginx apache or something similar that adds headers
