@sean-perkins Not related to this issue but trying 6.2.2 and 6.2.4-nightly.20220822 I have a new issue where useIonViewWillEnter is not executed...

@Janaka-Steph can you open a new issue with a reproduction so we can take a look?

@sean-perkins seems like there is an issue with the refreshers on pages with IonContent fullscreen which have a color.

Code to reproduce this issue:

const Tab1: React.FC = () => {
  return (
    <IonPage>
      <IonHeader>
        <IonToolbar>
          <IonTitle>Tab 1</IonTitle>
        </IonToolbar>
      </IonHeader>
      <IonContent color="warning" fullscreen>
        <IonHeader collapse="condense">
          <IonToolbar color="warning">
            <IonTitle size="large">Tab 1</IonTitle>
          </IonToolbar>
        </IonHeader>
        <IonRefresher slot="fixed" onIonRefresh={doRefresh}>
          <IonRefresherContent></IonRefresherContent>
        </IonRefresher>
        <div className="center">
          <h1>Tab 1</h1>
        </div>
      </IonContent>
    </IonPage>
  );
};
