You deleted the group "jira-software-users-acme".

Deleting the group “jira-software-users-acme” means that all the users in that group lose their product access to Jira Software1. This means that they can no longer perform any actions that require the Jira Software User role, such as updating an agile board2. The other options are not directly affected by deleting the group, as they depend on other factors such as personal settings, Confluence permissions, service project roles, and API tokens.
