Custom navigation buttons on Slide Master don't work

Hi Nicola,

So every slide in each scene has the functionality to jump to the previous scene or the next scene? I'm not sure I understand how they get between slides...but either way, the custom buttons should work. You'll want to check that you've applied that slide master layout to all the slides you'd like to use it If you right click on a slide and go down to layout, you'll see which one that slide is using highlighted. 

If you're still having difficulty are you able to share your .story file here with us? If you'd prefer to share it privately you can also send it here.
