The add-on needs a valid license to have all the provided features working. Valid licenses are subscriptions or 30-day trials and are available at the Atlassian Marketplace. The license model is the same as the one Atlassian uses for its products – for further information see Atlassian’s documentation.
To get a license and provide it for the plugin, please carry out the following:
Go to the license settings page (Settings > Apps > “Manage apps”)
Extend the “User Profiles for Jira” app
Use the links to create a new license at the Atlassian Marketplace (use “Free Trial” to get a new trial license - it will be converted into a subscription automatically after the trial period)
Without a valid license, a hint in the User profiles configuration will be explaining that the custom fields will no longer be updated, leading to outdated values being displayed over time.
