Netlify Serves Stale content even after cache purge via api

Hi,
We are facing netlify caching issue, even after purging the cache via purge/api. Our site details are as follows. We are use the netlify durable cache and you can see the configuration as follows.

initially we have setup the netlify-cdn-cache-control to

public, s-maxage=86400, durable
But we are receiving stale responses even after purging the cache via purge-api, so we added must-revalidate inorder to avoid serving stale content.

But still we see stale content being rendered. after the config i’ve attached the screenshots as well. Please check.

Netlify Site Name: https://qa-fnl-content.netlify.app
Next.js 14.

Our header config in next.config.js file

async headers() {
    return [
      {
        source: "/:path*",
        headers: [
          {
            key: "Netlify-CDN-Cache-Control",
            value: `public, s-maxage=86400, durable, must-revalidate`,
          },
          {
            key: "Cache-Tag",
            value: "common-tag",
          },
        ],
      },
    ];
  },

1st Request:

2nd Request:

Triggered the purge api now

3rdRequest:

This one was made after Cache Purge, if you see 2nd and 3rd request has no differences in response

4th Request:

Final Request after half-an-hour We expected this to happen at the 3rd request or 4th request.

So please help on the issue where we are getting stale content being served by Netlify-durable/edge even after purging.
