Application Insights not recording telemetry when added through Extensions in the portal
I created an application insights resource and then tried to link it to one of my web apps through the add Extensions option in the Azure portal. But, I was not able to see any telemetry being generated for the web app, even after 24 hours.
It however worked for me in another web app, but this time I had added the application insights using NuGet package in Visual Studio, instead of adding the extensions in the portal.

Observed that there are difference in the ApplicationInsigts.config file as generated while adding extension and while adding the nuget package.
