First, read the linked Reddit post (it’s very short). The user sees this behavior as shady black magic, something you’d expect from Facebook, perhaps.
But read the comments to learn what’s really happening, a clue to some of the behind-the-scenes on all the disparate Apple software elements working together on your behalf.
OP was deleted. What did it say?
About once a year, I’ll give Apple Maps a try, search for a business, it won’t find any of the several in Los Angeles, recommend 1 in Phoenix or Boston, and I’ll delete the app. That’s how Apple Maps works together with iOS and me. Google Maps is the only app capable of accurate and complete search results, and Waze is still the king of navigation (warning me of speed traps, etc.). I gave up hope for Maps, Numbers, and a few others from Apple.
