My goodness! Does no podcastplayer on iOS support chapters?
@devinprater Pretty much everything I've tried supports them: Apple Podcasts, Castro, Pocketcasts, Downcast, Overcast. Apple Podcasts is a bit fiddly though. Lossless Cut is the only app that lets me embed chapters in mp3 files so that they show up in AP.
Just a fun server for anyone associated with the blind community!
