I'm a project manager in need of creating some custom fields. My boss is a site administrator, we are trying to elevate my user to site admin as well so I have the right access to create custom fields.
Thing is, we can't seem to figure out how he can grant me such permission. Everything we find instructs us to go to admin.atlassian.com but all we see there is a CREATE form rather prompting us to SELECT an organization:

Note: Both myself (project admin) and my boss (site admin) see that same create form while logged in. For a brief moment it looks like there is a quick attempt to take us to the Atlassian Administrator settings but then suddenly we are redirected.
Any help?
I created a support ticket with Atlassian but who knows how long that could take.
Thanks in advance.
