p.s. May be it's not a bug with RNW, but I didn't find any information on the web, sorry.

Did you read through the release notes and look at the breaking changes? https://github.com/necolas/react-native-web/releases

@necolas sorry, can you clarify which point is related to this? (I read 0.8 and 0.7 breaking changes notes)

[necolas]

Make sure all the React packages are on the same version, and you have updated or removed the RNW babel plugin. There's no problem with the codesandbox or demos, so the issue is likely to be in your project configuration.

My problem was inside moduleNameMapper option inside Jest config in package.json

Not worked: "react-native": "<rootDir>/node_modules/react-native-web",
Worked: "^react-native$": "react-native-web",
