Argh... Working with #grafana V 11.3 is so frustrating.
1. Once you figure out all the panels you use are linked. So changing the query on one, changes them all on the others. First gotcha [You have to unlink the panel]
2. Then you encounter some wacky, buggy behaviour editing panels.
Changing query and parameters will fail to save the panel and you have to do some silly shenanigans like go to view the JSON file, or so something "meaningful" that the code then decides to save the panel.
3. And then there is a failure mode when the query changes take effect...but not the graph graphic attributes.
The workaround I found is to duplicate the panel, and the duplicate will properly execute the change.
Surely I am not the only one frustrated so?
