We've been using a Teams Bot to send back a typing reply in OnMessageActivityAsync. It worked until recently, doing it in this manner
protected override async Task OnMessageActivityAsync(ITurnContext<IMessageActivity> turnContext, CancellationToken cancellationToken)
{
await turnContext.SendActivityAsync(new Activity { Type = ActivityTypes.Typing }, cancellationToken);
}
As of recently, in new Teams, this no longer works. Does anyone have any idea why?
There seems to be an issue at the moment - see also this question from 2 weeks ago: Bot Framework Typing indicator is not working in new MS Team ( Work or School ) . I'm seeing it my side as well.
