Fontweights style not working

[baesslerpa]

import { PDFViewer, Document, Page, View, Text } from '@react-pdf/renderer';

function App() {
  return (
    <>
      <PDFViewer>
        <Document>
          <Page size="A4" style={{}}>
            <View style={{ fontWeight: 700 }}>
              <Text>Section #1</Text>
            </View>
            <View style={{ fontWeight: 'normal' }}>
              <Text>Section #2</Text>
            </View>
          </Page>
        </Document>
      </PDFViewer>
    </>
  );
}

export default App;

in production app im using

Font.register({
  family: 'Proxima',
  fonts: [
    { fontWeight: 'normal', src: '/fonts/ProximaNovaCondensed-Regular.ttf' },
    {
      fontWeight: 'bold',
      src: '/fonts/ProximaNovaCondensed-Bold.ttf',
    },
  ],
});

which either renders all fonts bold or none, depending on which style is first applied

opening a new issue, since all similar are closed.
using this minimal example, i still dont get the fontweights applied.
