Change map display

My map always starts in satellite view and historical rings round the stations, neither of which I want.
I can change then easily enough but the change only lasts through the current session and I have to redo the change next time I load it.
How do I make the changes stick? The old reliable “save” button is missing

Hi @Gordon_Stewart, once you have all of the settings you would like to keep on the PurpleAir map, you can save or bookmark the URL. Then, if you visit or return to that saved link, you will go to the PurpleAir map with all of your saved settings.
