I was doing my Japanese 2 routine and as I was going through the colors section on the desktop version I noticed that certain colors have no sound, as well as the multiple choice sound questions bug out and after clicking all three buttons I am unable to click another, but if I hit next it counts it as a correct answer. As well as the Listen to the sound and click the right word questions were impossible with no sound clip, I just clicked the patterns I recognized and they were right sometimes.
The are the colors that had no sounds for me:
Yellow
Black
Red
As well as these colors sometimes had sound:
Blue
Pink
These colors either had no sound at all or had sound on some of the questions. I hope this gets fixed, even though I know my Hiragana, for those that would still have a hard time with it they would probably get confused.
