I am performing a simple UnityWebRequest.Post, it works perfectly fine on PC and Android but not on iOS both in the editor and on the iOS device. Even with hard coded values, the WWWForm that is being sent to the PHP page is still null or empty. Again this is only a problem on iOS. Any ideas?

WWWForm Leaderboard= new WWWForm();
    		Leaderboard.AddField("score", highscore);
    		yield return new WaitForEndOfFrame();

    		using (UnityWebRequest www = UnityWebRequest.Post(score_PHP, Leaderboard))
    		{
    			yield return www.SendWebRequest();
    
    			if (www.isNetworkError || www.isHttpError)
    			{				
    				Debug.Log(www.error);
    			}
    			else
    			{
    				Debug.Log("Success!: " + www.downloadHandler.text;
                }
           }

For those who have the same problem I did, Unity provided me with the solution. Currently there is an issue with UnityWebRequest on iOS, the workaround is to use chunkedTransfer = false. That solved my problem.

using (UnityWebRequest www = UnityWebRequest.Post(score_PHP, Leaderboard))
             {
                 www.chunkedTransfer = false;
                 yield return www.SendWebRequest();
