Hi @homellc123, thanks for the post. Is this issue present with the Zoom client, or are you seeing in with the SDK? Thanks! ---

There is no problem with the Zoom client. I am using the SDK and I am using a custom UI. I don’t know how to solve this problem. ---

Hi @homellc123, Are you calling [`startAnnotation`](https://marketplacefront.zoom.us/sdk/meeting/macos/interface_zoom_s_d_k_a_s_controller.html#a516d9d29caafeebc903ce994de12dc51) before trying to annotate? If so, what is the return value of that method? Thanks! ---

When I call add comment it is successful. I need to close the current whiteboard first, and then reopen the whiteboard. At this time, other viewers can see the annotation I added ---
