Hi Lakshmi,
I tried to set up a demo to make it reappear but everything works fine if I put the exact same related code into demo project. Weird. However, when I tested it in a separate page inside my project, the problem appeared (only on UWP). Since the environments are the same, I guess some configuration/modules in the project may bother the rendering process.

• Syncfusion 18.4.0.43, Xamarin 5.0.0.2012
• VS Community 2019 16.8.5

I'll try to figure it out. If it relates to the expander control, I'll post detailed feedback.
Syncfusion.Xamarin is by far the best control sets ever. Thanks for you guys.

Update:
I did further debugging and realize the Expander actually got rendered. But because I put several expander in a vertical Scrollview, the Expander content didn't get stretched to its needed size automatically (the situation only exist on UWP).
I got a workaround by specifying a fixed HeightRequest for each expander and make the content scroll in horizontal direction.
Thanks for your help.
