Hi everyone,
Thanks for the reply. Regarding the issue you are facing, We are able to identify an issue for the situation you are mentioning. When the setMobileRTCRootController is not configured and the video preview feature has enabled(It is enabled by default), the join meeting process will struggle at presenting the video preview view. We will fix this in the next release.
As an alternative solution, please try to configure the setMobileRTCRootController (https://zoom.github.io/zoom-sdk-ios/interface_mobile_r_t_c.html#a74d0a3110932a0f9506b05d6e235b3ba ) or call disableShowVideoPreviewWhenJoinMeeting(https://zoom.github.io/zoom-sdk-ios/interface_mobile_r_t_c_meeting_settings.html#a85841243faa0e974b243ab093d53be88 ) to disable the video preview, this will work as expected.
Thanks!
