Tableau Reports not showing in iPhone and iPad in asp.net application

问题

I have an ASP.NET application in which I have embedded tableau reports with trusted authentication. These reports work just fine in all browsers, laptop and desktop. But on an iPhone or iPad whenever I am trying to open it, I get nothing.

I have searched a lot and tried all possibilities. I have embed=yes parameter but it's just not showing up. Here is my Javascript. In the label I am having a URL that looks like this (this is just an example):

https://online.tableau.com/t/Sales/views/test/test ?:embed=yes

I am use Javascript to find the div with id=viz and show report. What can I do to make it work?

function call()
{
  var viz;
  var vizDivID = document.getElementById('viz');
  var lbl = document.getElementById('URLLabel');
  var URL = (lbl.innerHTML);

  viz = new tableauSoftware.Viz(vizDivId, URL);
