I figured it out. I tried setting the <meta tags, but it never works.
It seems the issue is with the server setting cache headings. I made a change to the nginx sites-available file:
location / {
try_files $uri $uri/ =404;
add_header Cache-Control "no-store, no-cache, must-revalidate";
}
location /static {
expires 30d;
add_header Cache-Control "public";
access_log off;
}
