browserslist

"browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all",
      "ie 10"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version",
      "ie 11"
    ]
}

index.js

import 'react-app-polyfill/ie11';
import 'react-app-polyfill/stable';

According to the changelog for 3.0, it should fix everything for the defined browsers - in this case IE11.

Same here, just a simple hello-world with create-react-app is breaking in IE11.
