Has anyone else noticed that since Catalina, Maps is now continually triggering Location Services, even if the app hasn't been used? The little directional arrow in the menu bar keeps appearing and disappearing about every 30 seconds.
Anything that uses location services will trigger that arrow, not just Maps.
Go to Settings/Privacy/Location Services.
You will see there are many apps that may use location services.
Some even have a setting to use location scan for locations "always"
Be cautious about turning location services off, as you may create limitations for software that may affect how it performs. (Just something to think about - remember which apps you use a lot, and what changes you make to apps that might use location services.)
And, then you want to also look at the bottom of that list for System Services. There's lots of settings that affect how Location Services function.
Have fun -- keep track of what you change, so you can go back and turn some back on, if needed.
