Built-in Annotations & Alerts query not operating as expected

I have a weird issue on Grafana Cloud - I have a dashboard where the alert annotations were showing on all time series visualizations, today they are only showing on the visualization that is linked to the alert (I am sure I didn’t change anything!). The built-in query is still set to display on all panels.

I have tried:

  • Refreshing the dashboard
    
  • Refreshing the page
    
  • Enabling/disabling the built-in query
    
  • Changing the query settings to include/exclude panels.
    
  • Viewing the dashboard in Chrome and Firefox, in case it is a browser-specific issue.
    

None of the above has restored the annotations to the visualizations - is there another setting that I need to adjust?
