In my experience the new version of desktop seems less stable and less usable, especially in the use of shared documents and annotations, compared to the old version. What is needed is increasing the number of webcams for the presenter in the old version. It is less important for attendees to have access to all the shared webcams of other attendees. The emojis and hand gestures in the new desktop application are nice. However they do not present much real value.
I sincerely hope the old version of desktop will not be retired before the new version is improved.
