Example app does not works

I tried running the example the, the app does not seems to work. Probably due to very old dep versions.

Exactly what broke

1. yarn start server errors. Setting export NODE_OPTIONS=--openssl-legacy-provider and then restarting the server works.
2. Android build breaks.
3. Also the iOS requires very old set of xcode sim config.

I think upgrading the example app would fix this.
