Hi, @arfa.ahmed, Thank you for posting in the Zoom Developer Forum. To begin, can you share a screenshot of what you see _on iPhone 14 + iOS 16.4.1_? This helps us diagnose what may be happening. ---

Hey @arfa.ahmed It was a known issue prior to SDK 1.7.0, we have fixed it in 1.7.0. Did you update the dependent resources? I saw you were using self-served resources in the issue description. One way to check the following statement on the console: ```plaintext JsMediaSDK_Instance.version === '15.0.2712' ``` Thanks Vic ---

I have identified the root cause of the issue and fixed it. Safari 16.4 recently added support of [OffscreenCanvas](https://developer.mozilla.org/en-US/docs/Web/API/OffscreenCanvas) and we are using if (window.OffscreenCanvas === ‘function’) then render self video in video element otherwise in canvas. Now, we are using stream.isRenderSelfViewWithVideoElement() for this. ---

@arfa.ahmed , Glad you were able to resolve that behavior by leveraging stream.isRenderSelfViewWithVideoElement(). I am linking the support documentation on this topic for reference. I should note that there is an example implementation that works in all browsers and includes catch statements to help with debugging ![Screenshot 2023-05-01 at 7.18.40 AM](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/d/4/d43bff6146e792d477926d8e389cd46bcb29c7c2.png) ![Screenshot 2023-05-01 at 7.18.25 AM](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/a/9/a991e8dedaca9d03dceacc82acc520adddb30b73.png) [https://developers.zoom.us/docs/video-sdk/web/video/#render-self-view](https://developers.zoom.us/docs/video-sdk/web/video/#render-self-view) ---
