I am using the cascade template and wanted to use the 'dark' option for my text sections and overall app. However, when I do that, the appearance of my web map in the immersible sections changes dramatically- it's like the basemap I am using gets washed out by the dark background of the section. Is there any way to prevent this from happening? It only seems to be with web maps, not images. Also, it would be useful to change the background per section. I understand global settings are good and I would love to use them, but the way a dark background affects my web map is a deal breaker for me-- yet it looks better throughout the rest of my story.
