Hi @patuwwy Did you set a IndicatorView_Experimental flag? IndicatorView is preview state so need to set flag before init Xamarin.forms

        static void Main(string[] args)
        {
            var app = new Program();
            Forms.SetFlags("IndicatorView_Experimental");
            Forms.Init(app);
            Tizen.Wearable.CircularUI.Forms.FormsCircularUI.Init();
            app.Run(args);
        }

And We not support IndicatorColor, SelectedIndicatorColor, You can use only system default appearance

What is the reason for not supporting these properties? When creating an application we use non-standard colors and almost always have a problem with controls that cannot be customized. Please, add support for these properties.

Because, not supported in Tizen Native UI Frameworks https://docs.tizen.org/application/native/api/wearable/5.5/group__Elm__Index.html

We try to depend on only Tizen public API as possible as. to change a color, we maybe use internal api and it does not guarantee backward-compatibility, and also update color may not be possible.

We will consider to support IndicatorColor and SelectedIndicatorColor, if exist way to update

Thank You for Your support and useful informations!

That's what I missed!
