========================================================================== Update: 06/20 - Based on the links above, I updated Log4NET appenders to use ApplicationInsights appenders (instead of writing to FS). Removing this, clears the error, but Application Insights does not seem to work.
Do we need to update update Log4NET appender for SiteCore 9.1 AI integartion? Or "Sitecore.Cloud.ApplicationInsights.config", should kick-in automatically after updating instrumentation key and patch.
