I have a site collection that I am unable to locate in the SharePoint Admin Center. This site collection was created by someone clicking the "Create Site +" button on the home page. I am the Site Collection Administrator of the site collection, but am unable to "give" this site collection to the Admin account to make higher level changes that I need to make. Is there a way through the UI or Powershell that I can make SharePoint Admin level changes to this site collection?
Thanks!
