I downloaded a rather large deck on my android that contains audio on each card. When I sync, everything seems go well. Audio plays well on every card on android.
However, when I use AnkiWeb, on about half of the cards, the audio doesn’t play. The audio box is greyed-out.
I assume it’s a syncing issue, but I don’t know how to fix it. Syncing on my android doesn’t seem to work.
