Hi Mark and other commenters,
I have a similar issue. Back in Feb 2018, I worked for hours on a Storymap and I know I saved it, as I opened it later to show my husband. Today, April 2018, I went into my account, opened the map and can't see anything except tabs and title. My summary is gone, my points, my text, everything! And it looks different with the Shortlist Builder Beta at the top and the way it wants to import points. So maybe there was an upgrade between the time I created it and now, but where did everything I worked on go?
I tried to walk through Mark's steps listed above, however, the only option I have to share is public or private, no option to "create a web app." Also the map is listed in my content as a web mapping app. I can see it in My Stories also, but again, no data except title and tabs. It's all really disappointing. I have made Storymaps before with no problems. For this one, I added the data points from scratch, typing in the address to locate the points, then adding text. So maybe because I didn't put a photo with each it didn't save them? But again, I did show my husband a few hours later after logging out and back in.
Any thoughts or suggestions or ways to find all I already did is much appreciated! Let me know if there is more information or links I should attach.
TIA,
Alicia
