I have been using meeting-sdk for last three weeks. Now This week we have encountered a issue where on intial load the user is getting video option is disabled also the screen-share button is disabled.

This is very critical issue, As our whole user base is getting effected all our meetings and classes, Please look into it and let me know any solution. I have web isolation enabled and gallery and other views are also there but participant video is not working.

I have @zoom/meetingsdk
