The biggest problem I have with Apple Maps these days is how ignorant the report submission staff are. We have a residential estate here - miles from stores. Time and time again, I will see outlet stores pop up ... and viewpoints from highways tens of miles away plopped right on someone's house.
I report it. They ask for more info. I provide it. They sometimes reject it, or sometimes approve it.
And a few weeks later... the pins are still on the map.
I suspect they hire centres of overseas workers to rip through tonnes of these requests per day which might have differences in language / understanding, as well as perhaps no experience of some countries they are investigating the map changes for so they often probably just guess.
