@dattatray.deokar I also faced the same issue and found that initializing the Zoom SDK in background mode causes video rendering to fail. I resolved this by adding a check to ensure the SDK is initialized only in the foreground, not in the background

I’m Initialising Zoom SDK in didFinishLaunchingWithOptions and cleaning it in applicationWillTerminate. Now moved logic in applicationDidBecomeActive but issue is still there.

@dattatray.deokar @prashant.isavvy

Might be the same bug as [No Video Output ZoomVideoSDK](https://devforum.zoom.us/t/no-video-output-zoomvideosdk/120470) - please try out 2.1.10 once it’s released later this month.

Thank you for your patience,  
Richard
