Long tap event with FlowListView

[jamesingreersc]

Hi All,
I saw this previous post here #186
but never saw an answer.

They were 3 links given but none of them will work.

This is code I inherited from another developer and have to get a long tap event on a thumbnail page.
When I try an Effect or Custom Renderer I can get a long tap but that seems to short circuit the FlowItemTappedCommand which stops working. I can do a single tap in the custom renderer but there is a lot of existing code wrapped around FlowItemTappedCommand working. Below is the xaml code I am using. If anyone has any pointers I would certainly appreciate it.

        <controls:FlowListView
            Grid.Row                               ="5"
            Grid.Column                            ="2"
            BackgroundColor                        ="Transparent"
            FlowColumnMinWidth                     ="100"
            FlowItemTappedCommand                  ="{Binding Selected}"
            FlowItemsSource                        ="{Binding Thumbnails}"
            FlowLastTappedItem                     ="{Binding LastTappedItem}"
            HasUnevenRows                          ="True"
            SeparatorVisibility                    ="None">
