Summary:
We run into this timeout virtually every live-reload now, which I believe is just a function of the size of our React Native code base. Looking at the code, right now the prepare JS call is run and retried 3 times, with a wait/timeout of 1s each. On android, it's done 3 times with a wait/timeout of 5s on each. For consistency, I've updated it to be the same timeout as on android. Trying this with our project, we no longer get red-boxes when we live-reload for the first time.
I've run this on our project locally, and it fixed the issue. It's a very simple change, so I don't believe any additional testing should be needed.
