iOS-compatible extended vocab deck?

Hi friends-

I’m finally nearing the end of the core 2.3k deck for vocab studying and I’m struggling to find a good follow up deck. All the best extended decks I’ve found so far seem to use .ogg audio files which aren’t compatible with anki mobile on iOS which is really dumb (of iOS).

Any recs would be really appreciated thank you:)
