gzip encoded response is not working in iOS but working in Android

I'm using an API that is responding with gzip encoded data which is working fine in android but not in iOS. When I try to inspect the network call in safari inspector, it shows the response as in the attached image. 

The response headers received are :

content-encoding: gzip, gzip

Transfer-Encoding: chunked

Chrome is sending a request header Accept-encoding: gzip deflate when I make this call, but Safari doesn't.

Is this an issue with Cordova or Safari ? Is there a way to fix this ?
