Hi Alberto,

We are able to reproduce the reported issue "System.ArgumentOutOfRangeException" at our end and logged a defect report on this, and the fix will be available in our upcoming Volume 3 release which is scheduled to be rolled out in the Month of September 2018.

Thanks,
Manivannan E

Hi Anilkumar,


We have checked the reported problem “App crashed when zooming” and we are not able to reproduce the issue at our end. Please find the sample from the below attachment.


If still you are facing the problem, could you please revert us the modified sample with issue reproduced state which will be helpful to serve you better solution at the earliest.

  • Syncfusion package version,

  • Xamarin.Forms version and

  • Deployment target device version


Regards,

Yuvaraj.
