Hope it can be fixed.
Edited- sound issue is fixed and app developer did reach out with pointers. Not 5 star yet as my 5yo just isn’t too interested in the app. Will keep trying. So far disappointed. Looking for a great Spanish app. Bought this yesterday because of the good reviews, but there is no sound. I tried to remove the app and reinstall and now it’s asking me to buy it again. So frustrated trying to find a good kids Spanish app.
