I use a custom font to render emojis which works fine on both Windows and MacOS
.soundLink::after { font-family: myfont; content: '🔊'; font-size: 32px; } @font-face { font-family: myfont; src: url("_seguiemj.ttf"); }
however, it doesn’t work at all on my iPhone IOS 18.3
Have you checked to make sure your media – including that font file – has fully synced to your iOS device? Cloud Sync - AnkiMobile Manual
Hmm… quite strange. Im pretty sure the sync was complete last night, but after a whole night, when I clicked sync again, it prompted me to download from AnkiWeb, then the problem solved.
