How on earth am I supposed to work this

It like Doesn’t work 😭 Like I swear I miss almost all the notes bcs the touching mechanism for long notes doesn’t work,I have resorted to tapping he notes consistently to make the note long Also I didn’t even realize it was a long note at first Then Notes are way too close to thee color scheme which actually gives me a lot of trouble actually Tapping them 💀 Basically The rewards are so worth it but the game is Brocken 💔
