Shortly after Story Map Builder was introduced, I used it to create a few items.
The one I use the most is a show case for maps and apps I'd created in ArcGIS Online. I regularly share these via Twitter and usually a short video clip to demonstrate the map or app in action and include a link to it as well.
It had worked very well, showing each Tweet as a card in a media wrapper.
Today, all of these were blank. I looked at the HTML and it showed visibility: hidden !!!
I edited the HTML to change 'visibility: hidden' to 'visibility: visible' and the cards reappeared. However, when I publish the changes, they're not saved. This just looks like an error that's been introduced to the coding. Please can you find out what's going on and let me know asap?
