I am having this exact problem. I have multiple templates and use a DataTemplateSelector to show the correct one and RecycleElement and RecycleElementAndDataTemplate while correct the problem of the content not appearing, mess up with the layout of some templates. On 3.6 RetainElement and RecycleElementAndDataTemplate work as expected so, I am stuck on 3.6.
