Xamarin forms app becomes unresponsive when the system time changes while app is minimized

Any idea why changing system time while Xamarin forms application running background causes issues like the application are unresponsive and buttons are not working etc?

I started the Xamarin forms UWP application, then I switched it to work in the background. I changed the system time by subtracting a few hours. After returning to the application it was unresponsive and the buttons are not working. I debugged the application, but I didn't see any reason for this kind of behaviour. The same thing happens on Android and iOS. I am using Xamarin.Forms version 5.0.0.1874.

Steps to reproduce:-

1- Open Xamarin App

2- Go to your main page

3- Minimize app and change system time

4- Open App again and perform any operation if it is working correct Repeat steps 2 & 3

5- Open App again and observe it is now unresponsive

Is it Xamarin form related issue or it is happening for other frameworks as well?

Any suggestions/ideas on why is it occurring and how to handle it?

Hi, ShubhamKumar-7254. I cannot reproduce the issue on my side. I test the a basic demo and add a button in the mainpage to display a popup. After '2 & 3' steps, the popup will still be shown when clicking the button. How did you test the function? Please post more details about the issue. And try to update the Xamarin.Forms package to lastest stable version and test again.

I have updated the Xamarin.Forms package and still the issue is reproducible at my end.
