How to prevent ion-content ScrollBar-Y auto-hide

I have the next code:

<ion-content>
  <ion-list>
    <ion-item *ngFor="let material of materiale" (click)="closeModal($event)">
      <ion-label text-wrap>
        {{ material[1] }}
      </ion-label>
    </ion-item>
  </ion-list>
</ion-content>

I need to show always the scrollBar-Y but when I scroll it, it auto-hides.

Can you help me?

Thanks.

Hi @FcoCrespo,

does this work?

ion-content {
  overflow-y: scroll !important;
}

Thanks for your answer, but it doesn’t work.
It still is disappearing.
I think that’s because of the last version of ionic, because in youtube tutorials I can see perfectly the scroll bar , but Ionic version is 3 or 4.
