Repro application

When a Page containing a ScrollView is displayed on an iPad using Navigation.PushModalAsync(Page), the appearance of the Keyboard (resulting from giving a control on the Page focus) causes the content of the ScrollView to immediately scroll off of the visible screen...but only when the iPad's Home Button is oriented on the left.  Hiding the Keyboard returns the content to its original position.  When the iPad is oriented with the Home Button on the right, the ScrollView behaves correctly (i.e. the content remains visible).

+1 on this bug.

It also happens on iPhone 4/4s/5/5s when the device is on landscape position.

A workaround would be disabling the auto-scrolling behaviour and deal with the scrolling manually. Is there any way to disable it? Right now I'm re-scrolling after 500ms but this is very very bad, I can't ship an app like this.

I have checked this issue with Xamarin.Forms. and observed that this issue has been fixed. Hence I am closing this issue.
