Bug: delay in hearing sounds when testing vocabulary knowledge

I’ve noticed in the vocabulary reviews, when you are given a question where you are tasked with spelling out a word or phrase that is spoken by the AI, there is sometimes a long delay before the sound plays. Often the gap is so long (half a minute or more). I have tried clicking on the sound symbol to try to get the sound to play, but it won’t. Often I end up waiting for a while and then skipping that question (because I assume the sound is bugged), but then the sound plays while I’m doing the next question. It’s kinda frustrating to hear it and be unable to go back and answer the question.

Is this a known bug? Any idea when it might be looked at, and when we might expect a fix?

We’ll investigate the issue, thanks for reporting.
