Is there any way to report problems or get technical support for a mobile app? Open the problematic app on your device and check its menus for a link to “Support” or a “Contact Us” page. Select an app to get a pop-up window showing its information page and links to the developer. Microsoft’s mobile app store site for devices that run Windows 10 Mobile and Windows Phone software usually lists contact information for the software publisher and support links on each app’s page. The company also hosts support pages for its own apps, like its Microsoft Office Mobile software.
