I followed these instructions to install:
https://sqlperformance.com/2019/08/sentryone/plan-explorer-extension-azure-data-studio
I made sure my version is greater than 1.9.0 (mine is 1.43.0)
I installed .net 2.1 for MacOS
When I try to toggle on the sentry plan explorer I get this error : 'command 'planViewerAds.showInPlanViewer' not found". Does anyone know what this error means?
