Comment (by pauljacobson):

 A related issue arose recently that I initially reported on GitHub here:
 https://github.com/wordpress-mobile/WordPress-iOS/issues/9001

 == Expected behavior

 Embedded audio should play back correctly, without skipping, and
 restarting.

 == Actual behavior

 `mp3` audio files embedded using the `[audio]` shortcode are playing
 intermittently on iOS devices running iOS version 11.2.6 (and older). The
 audio player is loaded in mobile Safari on these devices. See
 `1043002-zen` for more context.

 User also reports that this issue occurs on new iOS devices running the
 current version of iOS.

 == Steps to reproduce the behavior

 Tested various audio clips on the same page. Audio clips are uploaded to
 the Media Library and embedded using the [audio] shortcode. Embeds are
 formatted like this:

 `[audio
 src="https://username.files.wordpress.com/2015/10/filename.mp3"][/audio]`

 The site is set to Private. Site privacy doesn't appear to have affected
 playback.

 Tested on iPad, iOS 11.2.6

 The site is running on WordPress.com, using the Dara theme.
