Thank you for your Feedback.
As a solution I could suggest you try the Telerik UI for Xamarin Blue Theme. For more details on this check the Setting a Theme article
from our documentation. Also regarding to the Xamarin Material Visual, could you please elaborate more on the requirements you have? How the Material theme should be applied to the Telerik UI for Xamarin controls? For example, like the Xamarin Material Visual or like the Telerik UI for Xamarin Blue Theme.
Do you want to have your say when we set our development plans?
