A. 1. Check Permissions: Ensure that DingTalk has permission to share your screen. Go to Settings > DingTalk and check if screen recording is enabled. 2. Restart the App: Close the DingTalk app completely and reopen it. Then, try to initiate screen sharing again. 3. Update iOS: Make sure your iPhone is running the latest version of iOS, as updates can fix bugs related to screen sharing.

B. 4. Use Alternative Methods: If screen sharing is still not working, consider using a different app for screen sharing temporarily, such as Zoom or Google Meet.
