Question: Where are the blank vowel and consonant tiles that I saw on the tutorial video?

Answer: Blank letter tiles are found in the alphabet. Double-tap the letter A it will change to a blank Vowel Tile. Double-tap the letter Z it will change to a blank Consonant Tile. The letter Y is both a consonant and a vowel. Double-tap the letter Y and it will change to a Consonant Y. Y will always default to the yellow Vowel Y in the alphabet.
