When new fields are added in the development system, they are not automatically shown in the Aha! integration mappings screen. Users do not intuitively know to click the "Reload configuration" button, and also do not know to check the Jira create/edit screens if the fields do not show.
Suggestion:
In the mappings screen, on the development system side of the field selections, add a "Field not found?" empty state when searching which provides a link to Reload Configuration
For Jira integrations, prompt the user to check the Jira create/edit screen configuration before loading configuration
