AnkiWeb not autoplaying audio

It shows the play buttons but audio plays only when you play it (unlike in desktop, it autoplays when you click ‘show answer’)

there’s another post with same issue Ankiweb not playing audio, the dude figured the audio files were not supported by AnkiWeb so he changed that to .mp3 but the deck I have, has .mp3 files. Help.

I was using this deck btw.

AnkiWeb doesn’t support automatic playing of audio at this time, in part because it’s not possible with mobile browsers.
