So, with all the buzz about the transition to the Unified Interface, I came across this issue where Url Command Action doesn’t work on the Dynamics for Phones app for a custom button

Scenario

I’m Url Command Action in the Ribbon Workbench’s custom button to navigate to a PDF User Guide stored on the SharePoint for users to simply click and navigate.

Now, this works fine on the classic Web UI and Unified Interface Web Application.

But doesn’t work on the Dynamics for Phones app! Nothing happens when you click on it.

Workaround/Resolution

So, the workaround is, using JavaScript method to navigate the URL as shown below

1. Write a JS file which uses Xrm.Navigation.openUrl(<link>); instead.
2. Remove the URL Action Command and use JavaScript Command instead in the Ribbon Workbench.
   
   
3. Sample Code here
   oAccountFormCustomization = {
   guideButton: function()
   {
   Xrm.Navigation.openUrl(“https://<yourlink/>&#8221;);
   }
   };
4. And this should work on your phone app when you click the button there and it should successfully navigate to the said URL (my SharePoint Document in this case)
