Hi all,

I am developing video call sdk in by app by zoom video call SDK. But for some device it will fire **ZoomVideoSDKError\_Session\_Join\_Failed** from **EventType.onError** event listener.

I am creating JWT token by using SDK\_KEY & SDK\_SECRET. by following below steps. [Video SDK Auth](https://developers.zoom.us/docs/video-sdk/auth/)

@chunsiong.zoom , also some time zoom don’t provide any event for join session. we checked some times ZoomVideoSDKDelegate not provide any update regarding join session.
