Cookie issue in the hybrid pages running within webview in ios app-Cookie set from native app to hybrid page

Hi Experts

We have tried setting a cookie from native app to hybrid page on (iOS objective c) to achieve that we have used following reference code from this link:-

https://objective-c.programmingpedia.net/en/knowledge-base/5954382/is-it-possible-to-set-a-cookie-manually-using-sharedhttpcookiestorage-for-a-uiwebview-

Also achieved, the cookies got set and it was working fine till November 12th, We haven't made any changes on code same code, also we are using same device having iOS14.

Suddenly cookie was stopped working, We do not have any clue why it is happening - Hybrid pages are running within WebView

Please help me on this.

Thanks
