Thank you for sharing the package manager message.
This states that the projects are using a version of Xamarin.Forms that is a little too old, 220.127.116.117273
. If you update all your projects to Xamarin.Forms 18.104.22.1687729
, you will then be able to install the latest release of the Telerik UI for Xamarin (2018.3.921)
