Hi when i update my grafana from 8.1.4 to 8.2.0, i found Graph used ‘aws cloudwatch datasource’ not show any data

then it can work:

Hello ollylu, Did you get this resolved ? I’m now witnessing same after patching Grafana v8.1.5 → v8.3.1

AWS metrics seem not updated, but going thru “edit” one can get this visible. However page is again blanck if browser reloaded
