Thanks for posting! This is a known issue and will be fixed in the next version. For your concern, please see the change log and post below for guidance :
One question there is line, “If you are setting the dependent assets to the Zoom CDN, there is no issue. For example:
ZoomMtg.setZoomJSLib(‘https://source.zoom.us/2.2.0/lib’, ‘/av’);”
Glad to hear that resolved the issue. Regards your question, are you asking what is that setter used for? If so, it is used to set zoom default requirements lib resource. To learn more you can check the Zoom Web SDK Reference here:
