title: Issue with ActionTypes.MessageBack in Microsoft Teams?
body: <p>I am using 3.11 version of Bot Builder with C#. I have an action button of type ActionTypes.MessageBack with below attributes.</p>
  
  <pre><code>cardActions.Add(new CardAction()
  {
      Type = ActionTypes.MessageBack,
      Title = "Update Est. Close Date",
      Value = JsonConvert.SerializeObject(data),
      Text = "Update Est. Close Date"
  });
  </code></pre>
  
  <p>When i click on the button, bot echoes back with "Update button" text in Microsoft Teams desktop versoin. But that is not the case for Microsoft Team in iOS. Is this an issue with MessageBack action type in Microsoft Teams? Please help.</p>
  
  <p>If you see below when user clicks on "Update Est. Close Date", i see an echo of the same text from Bot to User, in Microsoft Teams application in PC, but not in iOS.
