hi, i cant comfortably debug on Android because there are no sourcemaps in Chrome Dev Console. i tried several app-scripts versions but all the same put --dev in the package.json at build. even tried from blank projekt but same result, ionic serve --dev brings a webpack sourcemap, but only JS no typescript anyone some suggestions?
