This issue boiled down to the "Open link when clicking welcome notification"
feature not working, when you clicked the notification is opened the 'default'
URL, not the option set.

After doing a bunch of digging, I was able to confirm that we were saving that setting
and then servcing it to the SDK via the sync API.

I was then able to trace it through:

1) src/shared/helpers/EventHelper.ts (onSubscriptionChanged_showWelcomeNotification)
2) src/shared/helpers/MainHelper.ts (MainHelper.showLocalNotification)

There we shovel that url into a dataPayload that we shovel into a service worker call.

That comes out the other side when you click the notifiction in:

3) src/sw/serviceWorker/ServiceWorker.ts (onNotificationClicked)

There we cast via:

const osNotification = event.notification.data as IOSNotification;

IOSNotification is defined to have:

```
readonly launchURL?: string;
```

However, the struct we created had:

```
    const dataPayload = {
      data,
      url,
      buttons: buttons
        ? convertButtonsToNotificationActionType(buttons)
        : undefined,
    };
```

url != launchURL

Fixing the payload made it start working.
