Also I get the general principle but unsure specifically why this would have caused glare to break - would have been good to explain this in the PR description. I spent a while staring at the changes trying to work out what was related to glare, before realising when I looked at the individual commits.

Sorry, about that, I was a bit tired of this when making the PR, so I somehow didn't do that... The problem on the js-sdk side was that it tried to add a track to an undefined peerConn. On the react-sdk side, the problem was that I didn't properly handle call changes which lead to VideoFeeds having an undefined feed prop

The other changes were the things that I discovered on the way which confused me

Ah - makes sense, thanks
