I wonder if anyone else is having this issue? I will be at a bus stop/train station, and tracking the vehicle in Apple Maps, and all of a sudden if it says there is less than say 3-5 minutes remaining, the bus/train just "falls off" the map and it shows me the next one that is coming instead. Is this just to prevent people from running for a bus or something? This does not happen in Transit, Google, or my local transit agency's app. So I assume the issue is with Apple.
