I've posted on reddit about this behavior, I've submitted feedback to Apple countless times, I've scoured the web high and low and no one seems to know why or how to fix the issue. I sense that this is intended behavior otherwise it would have been resolved long ago. If it has forgotten it, I will not get the prompt. If Apple Music still has the last song played qued and ready to go, I will get the now playing prompt on the lock screen. I know now that it this is related to Apple Music not remembering the last song played because the two consistently go hand and hand. Apple Music still will not remember the last Apple Music track played and worse yet unless I was playing music on my iPhone within the last 30 minutes or so I will not get prompted to play music on my lock screen when I connect to my Bluetooth adapter in my vehicle. I'm now working with an Apple Watch Series 3, iPhone X and a newly replaced Bluetooth adapter for my car. I've even gone so far as to upgrade all of my devices related to the issue including my apple watch and my Bluetooth adapter in my vehicle. I've tried everything I can think of to fix it hoping that one day Apple would resolve it in a update. I've been working with this issue now since Apple Music was conceived and released to the public. This feature doesn't work after Apple Music forgets the last track that I've played. You know the feature where iOS tries to predict what you want to do next based on connected devices or environmental cues? For instance if I pug in headphones I get a now playing pane on the lock screen. it completely breaks iOS's prediction ability. Realistically, this isn't a huge issue at first glance as it takes little effort to fire up a Radio station again. It makes me believe that it is the intended behavior of the App. No amount of updating upgrading or reinstalling has resolved this issue. This is the consistent behavior of the App for me and has been since the inception of Apple Music.

Only it will only remember what had been played from the iTunes/Match library and not what had been playing from Apple Music. So Music does indeed remember the last song played. I also want to note that it will default to the last thing that I played in my iTunes/Match Library. If I don't interact with Apple Music for approximately an hour or so and then come back, it will have forgotten where I left off. Then I pause the station and leave the app. Here's the scenario: lets say I open Apple Music and play a radio station. I've noticed that this is related only to tracks on Apple Music/Apple Radio. I believe, just as Simon does, only I have much greater detail and I have both update my OS several times, I've completely reinstalled and I've upgraded my iPhone. I'm also experiencing Apple Music amnesia.
