Hi,

We’ve linked our Angular-based application with the Zoom Web SDK, but we’re having trouble with the following:  
When everyone joins the meeting through our integrated application, there is a lag in voice and video. When multiple users join using the Zoom app, audio and video lag is minimal. Our entire group is in India.  
The messages in the chat window do not scroll like they do in the Zoom app.  
Although the presenter is full screen in the participants’ devices, the presenter does not take full screen in its own system[.](http://wholesaleshopping.co.uk/)  
If some users join via our integrated app and others via the Zoom app[,](https://www.smokeryard.com) the chat will have a foreign flavour to it, and the video and audio will be distorted.  
When using the iPhone or Mac, the zoom window does not appear.  
The Record button only allows you to record to the cloud; it does not allow you to record locally.
