Using an iPhone 6, I received a call which went to voicemail, and the caller apparently left a message. I say "apparently" because when I go in to the voicemail app, the message won't play. If I click the "play" button/icon, the icon changes to the "pause" icon, but otherwise nothing happens and no sound plays. The progress bar shows a 32-second message, but it doesn't advance.
I exported the message to Voice Memos but that app exhibits the same behavior when attempting to play the file - the progress bar doesn't move, and no sound is played.
If this was just a normal audio file, I would guess the file is somehow corrupted (although apparently the metadata is OK). Are there any strategies I can use to try to recover the file or otherwise play the message?
