Did you manage to find a solution? I just deployed my app to AWS Amplify and I am running across the same issue. ---

I have changed ```auto await zmClient.init("en-US", `${window.location.origin}/lib`, 'zoom.us'); to await zmClient.init('en-US', 'Global'); ``` It works normally but does not use the **`lib`** in local. 😷 ---

Hey @phucnd , That is correct, you can either host the assets yourself and provide the path to them in `zmClient.init()` or use our CDN. 🙂 -Tommy ---

Hey Tommy, I just confirmed that I can access the files from the /lib which is placed inside my public folder, however, the exact same issue still persists. I would not mind using your CDN, but when I replaced the local path with ‘GLOBAL’ when the GET request is sent to the CDN, it returns error code 403, so I can’t access the CDN either. Could you help with that? ---

I also just tried to replace ‘GLOBAL’ with the CDN link like so ```auto await zmClient.init("en-US", 'https://dmogdx0jrul3u.cloudfront.net/2.0.0/lib'); ``` It works perfectly fine locally, however, when it is deployed to AWS I get this error: ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/2/e/2e1e341d3a1aa9d4b28f5e37a0b2c4f1494f2f79.png) ---

I finally got it to work! I used the Chrome Origin Trials to enable SharedArrayBuffers and it works as expected now! One question though, it seems like when I use my phone’s browser, I can connect to the meeting and see my phone’s video through my browser, however, I cannot see any of the participants’ videos through my phone’s browser. Is that behavior expected? ---

Hey @poufy , Happy to hear you got it working! 🙂 Unfortunately the Web Video SDK do not support mobile browsers at this time: [https://marketplace.zoom.us/docs/sdk/video/web#browser-support](https://marketplace.zoom.us/docs/sdk/video/web#browser-support) Thanks, Tommy ---

I see. I actually read the label that mobile browsers are not supported, but when I connected and managed to see my phone’s video from my browser I thought I could somehow get it to work. I assume that is not possible if there is no support for it yet. ---

Correct @poufy . It is not fully supported. That being said, mobile browser support is one of our priorities. Stay tuned! 🙂 -Tommy ---
