I had the same issue. In the developer menu (open it by shaking your device) you need to go in Dev Settings then Debug server host & port for device. There you need to enter your local ip address followed by the port (for example 192.168.1.10:8081). You can find your local IP address by running ifconfig in a terminal (you can find it under en0 I think). Your device and computer must also be on the same wifi network.

RN updates also comes with Native OS templates updates, try running react-native upgrade to update your iOS/Android files.
