Send closed captioning by REST API, but client unable to receive CC in real time

Hello
i read the page: https://support.zoom.us/hc/en-us/articles/115002212983-Closed-Captioning-with-REST-API , i send some CC to zoom meeting successful. But zoom client can not show the CC timely . There was a delay of more than two minutes . Is there a solution to this?

Hey @chenxunkun,
