Screenshot would show the users current location, and would not tell you anything that the directions didn't tell you. I followed the directions in that comment and confirm that I see what is described. A cloud icon in a top nav bar, on the right side, with a slash through it in my case as backup sync is off.
Appreciate the concern, but it was easy enough to zoom the map onto an empty part of the ocean and conceal any personal info.
Sure. Here's a screenshot when I have timeline view open (zoomed onto an ocean, that's why it's all blue): https://i.imgur.com/Yx9eBIg.png
The cloud had a slash through it, I tapped it and enabled the setting.
