Syncfusion.SfPdfViewer.XForms.Droid.ScrollViewEx.DispatchConfigurationChanged

Question

Hello,

My application is facing this failure, I am having this failure since the implementation of the package in my project. I wonder if I'm doing something wrong or if it's something wrong with the package?

Hi David,  
We are still unable to reproduce the issue,” Application crashes exception while Loading a Pdf document in Android Platform” in our end with the details you are provided. However, based on the provided stack trace, we suspect that this issue may be same the issue which we have faced recently, where application crashes with exception while changing the device orientation when SfPdfViewer control is placed inside the SfNavigation drawer control. 
Kindly let us know whether your replication scenario is same as above one?. If it is different from the issue which you are facing, kindly share the following details to analyze more on this issue and assist you with the better solution   
1.Simple sample/ modify the above sample to reproduce the issue.   
2.Replication video/ procedure to reproduce the issue.   
3.SfPdfViewer and Xamarin.Forms version

After many tests I ended up discovering what is causing this failure, when the device is enabled the screen orientation function and you change it causes this failure I inserted the video with the failure.
