Same for me

[Mehdi-KHALFALLAH]

same here, is it now required to run the metro bundler manually?

[MarcosGomesDev]

just working with yarn start after press a or npm start after press a, if try yarn android or npm run android it's crashing

o mesmo aqui, agora é necessário executar o empacotador metro manualmente?

[JavoxirNazarov]

same

[james-cohen]

Same. Unfortunately using react-native start isn't sufficient because I can't pass Android or iOS specific parameters. Having to run metro manually in one terminal and then open another to run the platform specific command isn't ideal

same issue

[fabOnReact]

There is already a PR that fixes this issue react-native-community/cli#2198

[cortinico]

As mentioned by @fabriziobertoglio1987,
this is a known bug. The fix has already been merged:

• fix: packager starting when using run-ios and run-android react-native-community/cli#2198

It will be shipped in 0.73.1 in the near future.
