I have a project that uses has templates which are added to the SfRotator. The page layout is as follows:
It is setup using Grids and Grid Row definitions to simulate a Top,Content (Middle) and Footer (bottom) layout. This layout works perfectly fine in UWP and IOS. The green bar and "Next" button can be viewed correctly in UWP and IOS. See below for UWP and IOS images respectively:
However in Android the Navigation thumbnails overlap the "Footer" section of the layout so that the green section and "Next" button is not visible:
I have attached a test project file that I have been using to test this.
