If I create a story map tour and embed it on my company's website, will the embed code still work/ story map still live online after my 60 day trial?
More so than the Story Map Tour,
1. Are you going to be publishing hosted feature services to ArcGIS Online?
This will expire and be disabled from access for you when the Trial period is over. Therefore the links inside the webmap which contain the data will no longer function and display the data.
2. The URLS to your story map tour, to your webmap should no longer use the Organization name in the URL. It should be truncated to https://www.arcgis.com.
Thanks,
