Line break in button

Ionic Framework ionic-v3
1

Hello,

I have a button with icon and text and I want to display the text under the icon.
On the Chrome browser it will be displayed correctly but not on IOS device.
No line break is made on IOS device.
What I made wrong?

<button class="tile-button button-inner" ion-button>
  <ion-row>
    <ion-col>
      <ion-icon name="info"></ion-icon>
    </ion-col>
  </ion-row>
  <ion-row>
    <ion-col class="title">
      Info
    </ion-col>
  </ion-row>
</button>


mytile {
  .tile-button {
    width: 15vw;
    height: 15vw;
  }

  .button-inner {
    flex-flow: column;
  }

  .title {
    font-size: 2vw;
  }
}
