Tl;Dr Spotify turned shuffle on after I closed the app then later resumed my listening leaving me wildly confused and possibly with some major spoilers. Check before you resume listening.
I did a longer road trip this weekend and decided it'd be a good time to get through some of the books in my backlog. Unfortunately, not only was I hit with my audiobook listening limit (15 hours per month, apparently), which is not something I remember Spotify advertising very clearly in the app, but also Spotify decided to turn on shuffle on my return trip. Since I was paying attention to the road I honestly thought that perhaps the author had decided to go with a disjointed narrative for the latter half of the book, but when I got home I found that I had inadvertently listened to a few later chapters, and now I'm a little upset about it.
The book was The Luckiest Girl Alive if anyone was curious (honestly the jumpy timeline narrative kind of worked, it was just a little confusing). If you're new to this one, it comes with a pretty big content warning just fyi.
I guess I'll be finishing it next month when I have more listening hours on Spotify.
I loaded my audiobooks into my Emby server and had that happen to me once. lol. Luckily it wasn't too much work to reset the "played" status and get back on track.
