As the title says, some users cant see linked issues in one specific project.
If they go to the other project, they can see the linked issue from the original project.
All of the users (who can and can not see linked issues) are in the same group (Group in User management part of Jira) that have the Developer project role (People tab in project settings), that project role has permissions to browse both projects and to edit ticket, comments etc. in both projects.
Can anyone please let me know what else should I check? This seems very illogical. Thank you.
