After a few seconds, open the Zoom app again.If not, you might have to wait until things are fixed. For this, head over to Zoom’s status page and make sure everything is operational. Thus, it is vital to ensure that things are working on Zoom’s end as well. Though rare, it is possible that everything on your end is fine, and the problem lies at Zoom’s end. If your internet is slow, or you are downloading or uploading something or streaming a movie on another device connected to the same Wi-Fi, please consider stopping these during the Zoom call. Tip: The faster the internet, the better the Zoom experience.
