If there are only a few people not able to view Tempo, you might want to check if they have Tempo Timesheets Access permission. To check on this permission go to: On Cloud: Jira Settings > System > Global Permissions > Tempo Timesheets Access. On Data Center: Jira Administration > System > Global Permissions > Tempo Timesheets Access. If these users are not part of a group that has the Tempo Timesheets Access permission, you'll need to add them to the group. |
