When adding a DatePicker inside a TableView, every time it is tapped it takes ~3 seconds to open the date selection popup.

Xamarin.Forms: Latest stable 2.3.2.127
Lumia 640 XL: OSBuild 10.0.14.14393.321

Might this be due to the large number of windows controls used in the forms layout implementations.
--> my layout looks something like this:

<ViewCell>
  <Grid>
    <Grid.ColumnDefinitions>
      <ColumnDefinition Width="2*"/>
      <ColumnDefinition Width="5*"/>
    </Grid.ColumnDefinitions>
    <Label Grid.Row="0" Grid.RowSpan="2"/>
    <Label Grid.Row="1" Grid.Column="0"/>
    <DatePicker Grid.Row="1" Grid.Column="1"/>
  </Grid>
</ViewCell>

Using a similar Lumia device I can see a delay which isn't quite as bad but not 100% instant, either. I'll set this to confirmed for now and in the future we can see how this might be improved, if future updates and changes don't indirectly help.
