Uploaded and embedded sound files (*.mp3) can't be played by the Moodle player properly in mobile iOS devices (neither iPad nor iPhone; iOS 13.5.1, but same problem before the last update)
The audio is useless because the play button "doesn't hold" - when you tap it, it plays only a very, very short sequence (maybe 0.2 seconds) and stops. If you keep tapping, it goes through the whole recording like that (plays one ultra-short snippet after the other).
Very, very occasionally and randomly the audio can unexpectedly be played as a whole, but then it is impossible to pause or stop it in the player (only stops after leaving the section).
This issue occurs in all activities/resources I've set up for my students: assignments, lessons, quizzes, pages, books and labels, so I guess it is a problem with the (set-up of the) text editor in general.
It works fine in my browsers (Safari, Firefox) and Moodle Desktop (on Mac).
I have tried additionally uploading alternative sound files (e.g. *.aac, *.ogg) but that doesn't make any difference.
P.S. This problem has been reported by two other moodlers https://moodle.org/mod/forum/discuss.php?d=405454#p1636598 , but the thread has produced no answers, so I'm taking it here as I believe this category is more promising. I hope this is ok.
