Android Kotlin Developer to fix a issue in an app bundle

HI,
Start your proposal with WEBVIEW, else it looks spammy.
So we have published a webview app on playstore built with Kotlin.
The issue we are facing is that the website cookies are working fine on the apk that is generated on the android studio but it is not working on the app bundle that we publish on the playstore.

We need urgent fix for this issue.
