cameras.

recommends configuring the camera before the meeting starts.

○ Video call or meeting
○ Share screen
To avoid audio choppy issues during the audio call or meeting, users are recommended not to perform the following tasks:
○ Move the application window frequently or quickly.
○ Scroll down the Microsoft PowerPoint slide, Word document, Excel sheet, or a website page frequently or quickly.
○ Play a video in an ICA session frequently.
