Scroll React

Trying to get scroll working in React with Ionic byt it wont work at all, no errors but list of cards i stuck.

class List extends Component<{ data: any }> {
  render() {
    const { data } = this.props;

    return (
          <IonToolbar color="primary">
   any) => {
              return (
                <IonCard key={}>

Any ideas?

Try wrapping your cards in <IonList> and see if that helps

Thanks for your suggestion but it does not change anything. Any other thought?

<IonContent class="scroll-content">

Does this help?
