I updated my iPhone to iOS 10.3 yesterday afternoon, and ever since then I have an issue where podcasts (played from "On This iPhone") stop playing after about ten minutes. There's no error message or anything, and the play-time clock continues to run sometimes. So far, this doesn't seem to happen with music.
I ran the diagnostic tool and got receipt #7238412. I have a Play:5, two Play:3 units, and a Play:1, all grouped together when this issue occurs. I also have a Boost hooked up.
I don't know if correlation = causation here, but I did not have this issue prior to updating my iPhone OS. FWIW, I have not updated the iPad I sometimes use to control my system.
Please let me know what you think.
