botbuilder-dotnet: ChoicePrompt : Choice values are not getting displayed on skype channel(both for skype windows app and skype online)

Hi All,

I have used choice prompt to show user choices and select one from it,

below is the code sample …

var strs = new List<string>{"Choice 1","Choice 2"};
var choices = ChoiceFactory.ToChoices();
                    await dc.PromptAsync("promptid", new PromptOptions()
                    {
                        Prompt = MessageFactory.Text("Prompt text"),
                        Choices = choices,
                        RetryPrompt = MessageFactory.SuggestedActions(
                            strs,
                            "Reprompt text") as Activity
                    });


 var choicePrompt = new ChoicePrompt(PromptType.ChoicePrompt.ToString(), this.ValidatorRegex, Culture.English);
choicePrompt.Style = ListStyle.Auto; // Also tried SuggestedAction 
this.AddDialog(choicePrompt);

While running this code on skype app on windows 10 the choice values are appear for couple of seconds and then disappear, before you can select it.

On Skype Online it does not show choices at all.

apps and Versions

Windows 10 Enterprice version 1803

Skype desktop app : Skype version 8.34.0.81 Application version 14.34.81.0

bot framework : 4.1.5

Could you please help me out how to use choice prompt with skype…?
