Microsoft.ApplicationInsights.AspNetCore - losing Exception/Trace data when upgrading from v 2.14.0 to 2.15.0

As the title says, when I upgrade my Microsoft.ApplicationInsights.AspNetCore Nuget package from 2.14.0 to either 2.15.0 or 2.16.0, I lose all telemetry on Exceptions and Traces. Has anyone else encountered this issue? It occurs when run locally or from our Kubernetes cluster. Changing the version back to 2.14.0 fixes the issue.

Any illumination on this issue would be much appreciated.
