Crashes now! Fix this, unacceptable for a pay app – LetterSchool - Block Letters Review

Crashes after pressing the green arrow. This is unacceptable since we paid for this app! Prior to this problem, my daughter age 5 loved this app and it has improved her handwriting and love of it immensely. Very disappointed, please fix this and I will change my review accordingly.
