It happens to me every time I plug in my iPhone 14 Pro into my 2014 Toyota Corolla. (Doesn’t haven’t Apple CarPlay by default). So as others have said it’s likely because the car. If I were to replace my stereo unit with one that supports CarPlay I hopefully and probably won’t have this issue anymore… thank god. I always thought it was Apple Music. Well, it partly is I think. I never had this issue with Spotify, rather, well Spotify would always start off where I left it. Apple Music almost always plays the first song in my library. It seems if I leave the app open on my phone, it will continue where I left off sometimes…
