Am building my app using custom view for iOS. I have build the gallery view using collection view and everything seems to be working fine. If the participant leaves the meeting I try to update the collection view with new data, sometimes the MobileRTCVideoView in my collection view takes time to update or goes black completely. I have default UI in my android app, view is updating properly in that.
I use the following piece of code to update the MobileRTCVideoView.
