I was working on my second awakening quest. I finished the quest “Following the Melody” but the next quest on the list won’t show up. Allegro is suppose to give me “About a Friend” but as you can see in the screenshot he has not. The quest isn’t in my “In progress” quest list either. PLEASE HELP 
I have this same issue but on a different quest in the chain. Awakening/Journey Quest - Unable to Continue
I was able to solve this, view my thread above.
