As per error message, MobX expects Symbol to be available in the browser, as per https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Symbol#browser_compatibility. It is available in all modern browsers, but if yours doesn't provide it, either use a polyfill (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Symbol#browser_compatibility), but typically it is an option in your build tooling, or downgrade to MobX 5.
