Can I use this app to suggest issues? In one of my projects I found a bunch of buildings that have either the wrong direction or the wrong coordinates. Think "Random street 1, 2 and 4 are next to each other, but Random street 3 is 500m away". But since it's a city I don't live in I can't go there in person and confirm.

You can report issues by long pressing and tapping "Create a note" which people will eventually review and fix.

I love this app and use it frequently. Great excuse to take little walks around town.
