I currently have the issue of UWP crashing when navigating back to the page that contains the sfExpander.
I have commented out the sfExpander and the application works perfectly fine. More specifically when I comment out the comment section of the sfExpander then the application works. I have attached a Demo application so that you can test.
1. Start application.
2. Expand 'read more' tag.
3. Navigate to 'Other' page using the menu.
4. Navigate back to 'Start' page. Erro will be throw here.
Further investigation allows me to believe that when you navigate from the page the children are not all removed.
