SharePoint Online people picker is not resolving anyone. I'm a tenant administrator and even when I try to add myself whilst trying to create a new site collection, absolutely nothing resolves when assigning an administrator. I get the following error:
No results were found to match your search item. Please enter a new term or less specific term.
This also occurs when I use the smtp address. By the way, these are not external users I'm trying to add. They are all internal users.
