I've made an express map with an aerial basemap, pinning features of interest. Each pin has a 'click here for more information', which I have linked to individual headings elsewhere in the same Storymap (using the URL). These URL links work fine when viewing the published Story on desktop, but they are dead when viewing it on a phone/mobile device (and in preview mode). You click the link but nothing seems to happen at all. Is this an issue others are having? Is there a fix/workaround? It's already frustrating we cannot just link to a Header from the express map pop-ups and have to use the live URL links.
