On cloud, access to worklogs of other users on Team-Managed (former Next-Gen) projects need to be given for each Project individually, see also Permissions needed to see other users' worklogs in Team-Managed (former Next-Gen) projects
However, if you need to see the worklogs of all users, you will need the "View all worklogs" permission for each of the JIRA projects you are reviewing. The 'View all Worklogs' permission for the Project is required to view other users' worklogs.
Cloud instances: Please, bear in mind that the permission could take up to an hour to kick in permanently even if it looks like it has already happened.
