iFrame and web resource support for mobile
You can add iFrames and web resources in forms and dashboards in a custom business app, and they will appear in Dynamics 365 for tablets and phones as well. For example, if you add a news feed to a dashboard in a custom business app, the news feed will also appear in the tablet and phone app.
