Some kind of cache problem ?

I have this page where PHP snippet with airpress code pulls the records from a view in airtable to display it.
But since a couple of weeks, when I add a new record that should be displayed with airpress it doesnt show right away. But after a while (hours or days I dont know) it gets displayed in the page as it is supposed.
It looks like a sort of caching problem.
I tried clearing the following caches : browser, Expired Transients, All Transients, and the site dynamique cache.
But it is still not working until a few days when it magicially is there.
I am tearing my hair out on this one as I need my info right away on my website.
