Ask HN: React Native on cross-platform production app? Mistake?

Our app is currently in Meteor (which has been great for its cross-platform (iOS, Web, Android) and hot code push capabilities). However, we are running into performance/UX/scaling issues and want to switch frameworks.

We are debating going native on all 3 platforms or using React Native. React Native has the hot code push and cross-platform advantages, but is it ready for prime-time? This is a production app with thousands of concurrents. The UX and performance is key. Our engineering team has both iOS/Android and JS experience (but no RN experience). Thanks!
