Within Confluence Cloud free, when a site is initially created you're unable to delete said space even if you're an admin/site-admin. The creator of the space is listed as "Former User" and not yourself.
- Create Cloud Free site
- Create initial space
- Attempt to delete said space
The space should be available to be deleted.
The space is not able to be deleted and there is no option to delete.
There is no workaround for this issue at this moment.
