This hasn't been my experience at all. Setting it up on a VM using their installation instructions (https://github.com/jitsi/jitsi-meet/blob/master/doc/quick-in...) was very easy.
Then I just hit the url and it worked perfectly.
The biggest surprise was when I tried to access that same page from an Android phone. It prompted me to install the jitsi app. After I installed it, it directed me to my jitsi server.
For me it was flawless and even better that I expected. It's a strong competitor to zoom because of the fact that it works right inside the browser really well.
