Hey @andy.ly!
Hope all is well! We just released a new version of the SDK: https://github.com/zoom/zoom-sdk-ios.
I tested this in the sample app and it looks to be resolved, would you be able to test it in the sample app as well to double check?
If you would like to update your application with the latest version please follow the steps here as there are some changes that must be implemented in your application to support this version if you use broadcasting in the SDK. Zoom crshes/stops working after few mins in the call after the update to iOS 14 on iphone XR
Also, we have noticed some users have experienced a crash upon joining a meeting in the new version of the SDK. We are working to resolve this as soon as possible.
Let me know if you have any questions
Michael
