I have just tested on the `local` version of the web sdk and am seeing the same issues. ---

Hey @edward, thanks for reaching out! This is a known issue and we are working on a fix. > [@Web SDK embedding zoom into our app not always working](https://devforum.zoom.us/t/web-sdk-embedding-zoom-into-our-app-not-always-working/5709): > > Description/Error We’ve embedded zoom into our application using the Web SDK and example found here [https://marketplace.zoom.us/docs/sdk/native-sdks/Web-Client-SDK/getting-started/integrate-the-sdk](https://marketplace.zoom.us/docs/sdk/native-sdks/Web-Client-SDK/getting-started/integrate-the-sdk). It appears to work, however if anyone minimizes the spotlight video (video of yourself) it freezes the main video view for the participant (video of other person). We’ve also found that audio does not always work or does not use the default audio device the user has chosen. It seems to be hit and mi… Thanks for your patience, Tommy ---

Hello, can someone help me about this issue. Zoom video works for a few seconds at the start of a meeting, then it freezes on me. Can still see everyone else on the meeting, and their video works fine, but this one is frozen. Only way to get it ‘moving’ again is to ‘stop video’ and then ‘start video’. It will work again for a few seconds, then freeze. Not at all tech savvy…but is there something we can do to get it working properly? Thanks in advance, this had been really difficult while working at home. Sandie ---

Hi, any updates on this?? We are using Zoom enterprise software to deliver our lessons We don’t want our students to skip the lesson by using the “Tab” switch to do the old “switcheroo” trick - absent themselves while creating the deception that they are present to the instructor. In the first place, there should not be such functions like freezing the live video stream while the video botton has been activated! Thank you. ---

Hello, I have implemented the zoom web SDK sample CDN version in my website, and I encounter a **serious problem** when I activate the video - the memory of the process quickly increase up to saturation causing my screen to freeze. When do you think you will fiw this issue? Thanks in advance for your efforts ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/6/6ab9a23a6287b8dda5f2d305f571accfadd1f0e1.png) ---

Hi Zoom Team, In a somewhat related issue, there is no minimized mode for Zoom app in iPAD. When trying to access other apps on iPAD, the zoom video freezes and enables again when the app is again opened. Is there a fix to this, like a pop out or minimized screen in Zoom. I basically want the iPAD user to continue using other apps without breaking their live video feed as its a mandatory compliance for meetings. Thanks ---
