We have used web sdk in our web application where both host and participants are forced to use web client to join the meeting. However when we host a session with 400+ participants we ran into an issue where audio and video started to break. This happened for almost all users including host. Later we did the same with 10+ users and experienced the same.
Majority of the users was using latest chrome on windows and android phones.
Our web app is built using Angular 10
