NJ Transit Train 854 Arrives at Convent Station with Angry Commuter - 6/28/23

As Train 854 crawled through in the station, a passenger (who was later seen flipping off an NJ Transit conductor) was alerting the conductor that the app said Train 854 was "cancelled". He then said to him, "We're here, so no" implying that the app was incorrect and that Train 854 is NOT cancelled.
The man then flipped off the conductor as the train was pulling away.
Frankly, I was confused too as to why it was considered "cancelled" even though it came in as scheduled. Classic NJ Transit at its core, I guess...
