This is my associated accounts page. No where I can see Meta Stack Overflow profile. But when I run /me/associated with meta_site as parameter to types, I get a response that tells me that I have a profile in Meta Stack Overflow, which is ambiguous.
Also, when I don't give types parameter, it will give me all the associated accounts (it is not given in documentation, but understood), i.e., if the account is in meta_site or main_site, it will give me all the accounts. This time it doesn't give my Meta Stack Overflow profile. Again ambiguous response.
types=main_sitein/me/associatedgivesmeta_siteaccounts also is another thing.
