Strange problem with max-age:0

Hi, I have a strange problem with my site, the homepage give me HIT but posts not, you can check (I don't have other caching plugins), from mobile site is blazing fast so caching is working but from PC not:

https://www.gaeta.it/festival-internazionale-propatria-la-14a-edizione-si-svolgera-nel-2024-in-sei-paesi

as you can see from PC the max-age is 0 also if I manually forced browser cache TTL in cloudflare to 120 secs and edge cache TTL to 1 year, in fact using external tools like https://dnschecker.org/server-headers-check.php the response header is correct.

WRONG RESPONDE HEADER:

max-age=0, no-cache, s-maxage=31536000
