What does “use flipper to debug” even mean? Flipper doesn’t have a way to connect to a debug port to set breakpoints. You still can’t do performance profiling. If “debug” just means see “console.log” statements thats a poor statement of debugging, I can see that in the terminal now. What does flipper even give you?

Have you tried using Flipper for debugging? Remote debugging in Chrome works by running JS code in Chrome’s V8 and connecting to the Bridge. We use Turbomodules (which don’t use Bridge at all) so Chrome can’t connect with the native side – this error is expected but could be described better. AFAIK Flipper should work with Android without problems on any recent RN version and iOS should work after RN 0.64.

EDIT: Seems like Flipper doesn’t work with Expo yet. If you need a debugger functionality you probably should wait with the Reanimated upgrade.
