Hello!
The issue of not being able to save changes when adding a story from a Demand related list after a ServiceNow upgrade to Xanadu (when it worked in Yokohama) commonly stems from customization conflicts with new Out-of-the-Box (OOB) features, outdated client scripts or business rules, or altered Access Control Lists (ACLs). Xanadu's platform changes can sometimes break existing configurations, especially if they were customized. It's crucial to check upgrade logs for skipped updates, compare customized files with OOB versions, debug browser console errors, and investigate security permissions to pinpoint the exact cause.
