What is DUILib? Is it required?

Hi lissette2402,

Thanks for the reply. Please have a try with the steps that I have mentioned in this post:

If you are still facing issues, since this is out of the scope of Marketplace App, and I do not have any visibilities regarding the issues happening in the Zoom client, please contact Zoom support at Contact Zoom Support - Zoom Support and one of the Zoom experts will be happy to help you.

Thanks!
