After updating to v7.12.0 on our JIRA-server instance, one user has reported that he cannot see a subset of issues in the active sprint board (tagged with a specific component). The user can see stories with the component that are not in the active sprint as well as all tickets without the component. We do not use any kinds of custom security measures on individual issues.
Anyone have any ideas on what could be happening, and how we could correct it?
