What benefits are there in downloading the app?

I am having quality problems when there are more than say 8 people on the chat. I am searching for ways to prevent these problems, including some people not being to enter the chat. Ideas I have are:

  • Make the chat voice only

  • Mute all the mics.

  • Reduce the band-width on each persons video

  • Download the app

I will greatly appreciate any advice to resolve these problems.

Many thanks
