Apple Maps, if you notice an issue with the information, route or directions, submit a report.
I’ve been solely an Apple Maps user for a few years (used all over the US) and honestly the only problems I’ve ever had are entrances to parks (i.e. baseball or large soccer parks that have numerous fields) where the directions may not end in an ideal location. But each time I’ve submitted a correction within a week I would receive a notification that it’s been updated. I would normally just take a screenshot of the correct parking lot or entrance and submit using the “Report an Issue” option.
I recently had to do it for a radiologist that moved and Apple Maps had the old location. The radiologist said that quite a few people say they get lost. I submitted an issue with the correct address and pin where it should be and less than a week received a notification it was fixed. Now if one of those lost people had just reported the issue, then I would not have been lost LOL. It helps us all.
