Even worse: here in Hamburg, a major German city with very high Google Maps usage, The S-Bahn line S1 is closed through the tunnel right in the centre of the city an entire month, and yet it has not been updated at all. Same thing occurred when the S1 from the airport to HBF was closed last month. These are very high capacity lines and it is tourist season. Anyone trying to use Google Maps is going to be very confused. Closures are only taken into account like 50% of the time.
Hamburg has almost half the population of Berlin, yet Google can't keep up with major scheduled line closures.
Google Maps has become noticeably worse at public transit directions in the last few years. In NYC it seemingly does not ingest service changes from the MTA API, I’ve had multiple friends complain about it.
Apple Maps is updated in near real time, I tell anyone who listens to use it for PT directions. The “Transit” app is great too.
