First off I am not having this problem. This is from a friend who is new to BiaB on Mac.

Steps to reproduce:

Write in the chords

Click on down arrow in the style picker.

Choose style picker (browse all styles)

Style does not change to new style. Old style remains


Question, what could I do to get this working properly.

First rebuild the Styles list by clicking the Rebuild button at the bottom of the Style Picker. Then after selecting the new Style make sure to click the Generate and Play button. If that doesn't help, we recommend your friend contact us directly. They can either email support@pgmusic.com or contact us via live chat.
