In the Android app, when starting a new activity (such as Classic Review), if the first screen/page of the activity plays a sound and you’re supposed to match the sound to a word/button, then the sound won’t play. (Rather, it seems like it tries to play, but gets immediately cut off before you can hear it - sound will come out of the speakers for the tiniest fraction of a second.) Clicking the large blue sound button at the top of the page/screen will not replay the sound (there is not even a tiny bit of sound). If there’s no prompt text under the blue sound button then it’s often impossible to know what response to give other than random guessing.
This doesn’t happen on later screens/pages in the same activity, only just the first one, and only that certain type of screen / prompt.
