Why do I see the pink „Nearby“ card even though I'm at home?

In that case a store was accidentally learned near your home, or a store's radius reaches all the way to you.

Fix it in an open list via „⋯“ at the top right → „Locations“ → „Manage Locations“: tap the offending location on the map and delete it, move it, or shrink its radius. If you never want a store at this spot, choose „Don't ask here again“ the next time „Are you shopping at …?“ appears.
