If you are experiencing a blank, green, or black screen when casting, it could be due to certain security measures or digital rights management (DRM) restrictions. In such cases, the app may prevent other apps from accessing the screen's content, resulting in the screen display issue.
Please try taking a screenshot of the page where the issue is occurring using the default screenshot tool on your phone. If you are unable to take a screenshot, it indicates that the app has restricted permission to capture the content of the page or app. There is no solution for now.
If you can make a screenshot successfully, kindly submit a request to AirDroid Support Team, and we will provide help as soon as possible.
