Hey lordjoe, the code actually looks good, and it should be working as expected. This code should create a custom span that measures how long it takes for this code to complete:
var apiRequest = this.CreateGetRequest();
var dashboard = await this.reportApiService.GetDashboard(apiRequest);
var result = this.Mapper.Map<DashboardGetResponseModel>(dashboard);
I saw that you have a support ticket about this as well, happy to set up a call and walk through it together. We can post the solution back here to help others.
