Typing indicator not going away in MS Teams channel

v4.4.3

Describe the bug

I was using a typing indicator in my chatbot wich worked fine. However, since a few days the typing indicator in MS Teams just keeps showing for 5 seconds, even when a message has been send; normally this wasn’t the case. The typing indicator still works in skype for bussines and webchat.

I used following code to start the indicator.

private async Task TypingIndicatorAsync(WaterfallStepContext context) 
       {
            var typing = context.Context.Activity.CreateReply();
            typing.Type = ActivityTypes.Typing;
            typing.ReplyToId = context.Context.Activity.Recipient.Id;
            CancellationToken a = new CancellationToken();
            await context.Context.SendActivityAsync(typing, a);
        }

Expected behavior

I want the indicator to go away when a message has been send by the bot.

@VKAlwaysWin Not much. The fix is done, but not still yet in public release rings.

I’m also still experiencing this issue in Teams, other channels work fine. The typing indicator disappears after a while, but it does not when an Activity is sent by the bot.

I first noticed this a while ago when using the desktop and web client, however recently this bug appeared on the mobile app as well. This issue also appeared when I created a new project based on the EchoBot example and added the typing indicator. I’m sending a TypingActivity using the following code:

await turnContext.SendActivityAsync(Activity.CreateTypingActivity());

Again, this works fine in other channels, but not in Teams.

Furthermore, I’d also like more information about the fix as @VKAlwaysWin said.

Thanks.
