Same issue.
I'm Organization Admin on site #1 and need to be the Org Admin on Site #2 also. I can't find where to myself as Org Admin role on site #2.
When I login as Org Admin on site #1 I see Settings > Administrators > Add administrators
When I login as the Organizational Admin on site #2 I can't access admin.atlassian.com. I have no products. I do Not see Settings > Administrators > Add administrators
I need help making me the Org Admin on Site #2 and removing the current Org admin.
Thanks
Heather
