When you add an application that is not downloaded from AppGallery to the AppAssistant, a risk dialog box is displayed

Symptom: When you add an application that is not downloaded from AppGallery to the AppAssistant, a risk dialog box is displayed, indicating that "You have installed an unknown source application, which has security risks." Or a gray exclamation mark (!) is displayed in the lower right corner of the application icon. 

Answer: 

This message or the gray exclamation mark (!) is used only as a reminder, which does not affect the AppAssistant or the application. This function has been adjusted for the AppAssistant. If you add another application that is being downloaded, this message will not be displayed. The downloaded application will still appear when the cache relationship is added, however, there is no other impact. Please rest assured.
