Current behavior

Changing a source using code like:

this.EventsListCollectionViewSource.Source = state.Data.GroupedCalendarEvents;

With corresponding XAML:

<Page>
    <Page.Resources>
        <CollectionViewSource
            x:Name="EventsListCollectionViewSource"
            IsSourceGrouped="True" />
    </Page.Resources>
    <Grid>
        <ListView ItemsSource="{Binding Source={StaticResource EventsListCollectionViewSource}}">
        </ListView
    </Grid>
</Page>

Does not seem to update the ListView content.

Expected behavior

ListView should be updated.

How to reproduce it (as minimally and precisely as possible)

Investigating.
