Custom Mapbox ID not working (WordPress plugin)

Hello.

I’m not sure if this plugin is supported by Knightlabs anywhere online, but I’m posting this support question both here and in the WordPress directory support in the hope that I can receive some help!

I am using the WordPress plugin version of Storymaps, and would like to implement a custom Mapbox style within this. For some reason, the conditional logic of clicking on mapbox:map-id to display the map-id field does not work. However, I am able to inspect the page markup to make the field temporarily available and insert my custom Mapbox id. I then save the page and this data is saved to the database as when I make the field appear (temporarily) again, I see my map-id there. On the front end however, I only see blank tiles.

Is anybody able to help with this issue?

Thanks,

Pete
