Doesn’t work

I tap the chord button, the chord is added to list on top, but no sound is produced.

I’m so happy to find this

This is exactly what I am looking for. I can practice the chords on my phone when I cannot keep the guitar on my hand. (Because I must hold my baby to keep her from crying). Thank you very much!
