There was a “mute” icon near the upper right on an audio test question (in the James W. Heisig - Remembering the Kanji 1 course, if that matters) and I didn’t know what it did, so I tapped it.
Apparently, I disabled audio tests. I cannot find anywhere in the app to enable them again. The FAQ on the web site mentions a “Learning Settings” screen in the app, but that doesn’t seem to exist, or if it does, I can’t figure out how to access it.
(Overall the experience of using the app has gone WAY down in recent versions. It used to be easy to use, but now it’s hard to use and disorganized. I always feel out of control with no idea what screen will appear next when I tap.)
Anyway, if there is any way to get to a settings screen or otherwise enable audio tests again, I would dearly love to know about it.
