My recent post are not updating

Hi,

I have recently uploaded some posts and when I visit my site from WordPress it shows the new posts in the homepage. However when I visit my site in the incognito tab I see the older posts on the homepage. What should I do? My site theme is Astra

Purged the cache from Cloudflare and Lite Speed cache

I have also changed the theme as well but the changed theme but website still comes with older theme.

I have also tried multiple browsers flushed their caches as well but nothing chnaged

Although my site map is updated and all the blog are indexed as well in google search console
