I’m trying to create a page that loads images remotely from an ObservableCollection. This works fine on Windows but crashes on Android emulator. I’m using VS 17.11.3. I read on github that this was a problem on 17.3 but it is supposed to be fixed. Is this still a known problem? Any workarounds?

<CollectionView
Grid.Row="4"
ItemsSource="{Binding RecommendedList}"
VerticalOptions="FillAndExpand">
<CollectionView.ItemsLayout>
    <GridItemsLayout
        HorizontalItemSpacing="5"
        Orientation="Vertical"
        Span="1"
        VerticalItemSpacing="5" />
</CollectionView.ItemsLayout>
<CollectionView.ItemTemplate>
    <DataTemplate>
        <Grid
            Padding="10,0,10,0"
            ColumnDefinitions="1*,10,Auto"
            RowDefinitions="Auto"
            RowSpacing="5">
            <Image Grid.Column="0" Aspect="Center">
                <Image.Source>
                    <UriImageSource Uri="{Binding ImgUrl}" />
                </Image.Source>
            </Image>
            <Label
                Grid.Column="2"
                HorizontalOptions="StartAndExpand"
                Text="{Binding Title}" />
        </Grid>
    </DataTemplate>
</CollectionView.ItemTemplate>

This is shown on github.com – https://github.com/dotnet/maui/issues/1260 but should be solved. I’ve checked the uri’s in question and they are all correct.
