When I sign into the Dynamics 365 CRM on my phone app, I'm unable to exit the Home Screen. I can slide it side to side, and I can access the eBooks, videos and more, but I'm unable to x out of the page no matter what I do. I see my program behind it, but can't get to it. I've deleted the app and reinstalled it twice. The program works great on my Surface and I Pad with no issues. No one can seem to help me.
