Hey @muellseb Thanks for your feedback. Could you test with our [sample-app](https://github.com/zoom/sample-app-videosdk/tree/master/react-demo), will the same problem occur? Thanks Vic ---

Hi @vic.yang no i did not. I already updated to SDK version 1.2.3 after I have seen your changelog. The issues are fixed with that version. 1. Audio and video not reconnecting properly on failover 2. Known issue with the video stops playing and goes black when resolution changes to or from 720p > **[web – Zoom Developer Support](https://devsupport.zoom.us/hc/en-us/sections/9481948737421-web)** Now I am facing another issue. User 1 joins a session and switches on the camera. User 2 joins the session. Everything is rendered correctly. User 2 leaves the session and re-joins. The dimensions are calculated correctly. But the video of User 1 takes the whole size of the canvas with the video. The avatar dimensions are correct. ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/3/6/36b09cf98a83d55fc71ba64db257959be1c7d736.jpeg) When I resize the window, the video is adjusted to the correct dimensions. ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/5/1/519cdd58ffc2e6a29c83cc05792a3e86dea87f1f.jpeg) any idea? ---

@vic.yang@tommy I made the very same experience in the sample app. Seams like a bug. User 1 joins and switch on camera ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/c/1/c140f60f8a1bdf1d53e0f6f3cf85374c6d9d24d2.jpeg) User 2 joins and everything is fine so far. ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/f/0/f01dbaba4f622a73b8823ad3ba19dcc8dbebaf11.jpeg) user 2 refreshs the browser. ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/5/9/59d6555503a759e7f0e32dd4568214dc79d993f2.png) user 2 joins again. ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/e/2/e2de1854ab6e97d44702e25cbe292da8cdd5a204.png) Result: ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/4/6/46de56488d114334208ec963e1620d1a689afaa9.jpeg) ---

Hey @muellseb There are some issues with the sample-app, we left out the logic to reset the `mediaState` when leaving the session, so next time when joining the session, the `isVideoDecodeReady` is falsely treated as `true`, but actually, it is `false`. We have updated the sample app, you can check the [change](https://github.com/zoom/sample-app-videosdk/commit/e15fb6e12099f76f90aaa2dd44b3e664acf81dfc). Thanks Vic ---
