if my rotator defined as below and i have images inside rotator, while it is autoplaying and looping, if I tap an image, exception is thrown on android. I am using XF version 2.3.3.193

SfRotator rotator = new SfRotator()

{

NavigationStripMode = NavigationStripMode.Dots,

NavigationDelay = 2000,

NavigationDirection = NavigationDirection.Horizontal,

NavigationStripPosition = NavigationStripPosition.Bottom,

EnableAutoPlay = true,

EnableLooping = true,

EnableSwiping = true,

Margin = new Thickness(30, 10),

VerticalOptions = LayoutOptions.Start,

HorizontalOptions = LayoutOptions.Center,

HeightRequest = Device.Idiom == TargetIdiom.Phone ? 300 : 500,

WidthRequest = Device.Idiom == TargetIdiom.Phone ? 300 : 500

};

An unhandled exception occured.
