Apple Users

Updated to ios 15, and the ugrade set a whole lot of apps to share my location "when shared" whatever the heck that means, and in all of those cases, "Ask Next Time Or When I Share"

My approach is to never give out my location except to things like maps, and wallet, find my phone, and OBVIOUS ones WHILE USING.

Since I don't understand "when shared" I just turned all those off.
If you don't understand it, don't enable it.
Easy enough to undo if needed.

Lots of apps ( like scanner apps) want our location automatically, but it's easy enough to click it in.
For example, I don't let the weather app access my location. I plug in a few locations of interest, and that's all it needs.

Apple does a lot of things "on your behalf" when you upgrade, and that's what makes upgrades a pain in the ass.
You often have to go and undo some decisions they made for you.
