Any progress on this?

Also just hit this. I have been playing with MAUI for about 2 hours and so far ran into at least 5 bugs for UWP. What's going on here?

Anyone have a workaround for this?

I thought MAUI's Windows backend was WinUI, not UWP?

I have the same problem. Any Updates to this ? Any workarounds ?

I have this problem as well. I thought that perhaps the RemainingItemsThreshold might need to be more than the number of items loaded initially but they don't make any difference. But apparently you need to wrap the collectionview in a refreshview? <RefreshView Grid.Row="0" Grid.Column="0" IsRefreshing="{Binding IsRefreshing}"> <CollectionView
VerticalOptions="Start"
ItemsSource="{Binding BatchItems}" SelectionMode="Single" SelectionChanged="CollectionView_SelectionChanged" VerticalScrollBarVisibility="Always" RemainingItemsThresholdReachedCommand="{Binding GetNextItemsCommand}" RemainingItemsThreshold="50" > etc

Same problem here. I worked around by placing a button underneath the CollectionView for now:

<Button Grid.Row="2"
        Text="Load more..."
        IsVisible="{OnPlatform False, WinUI=True}"
        Command="{Binding LoadMoreDocumentsCommand}" />

Also hoping/waiting for this to get fixed

This is somewhat funny, because WinUI is actually the only supported UI developed by Microsoft and it is also the platform with the most quirks when using MAUI. There really needs to be more/better support for desktop (WinUI).
