Cookie is not working

When I fetch using a custom cookie in plugin, it is not working. It is always giving the same result no matter what the cookie is.

curl -s "https://www.jiosaavn.com/api.php?__call=webapi.getBrowseHoverDetails&_format=json&_marker=0&api_version=4&ctx=web6dot0" -H "Cookie: L=telugu"

Above fetch should give different result than without the cookie. In MusicFree, both with and without are giving same results.

Note: I am from India and above endpoint will work fine in here.

fetch the above given link with and without the Cookie and compare the results.

Android 15 MusicFree v0.6.2
