I'm using the API get inbox messages and notifications for various sites on the StackExchange network, but it doesn't seem to matter what
site parameter I pass in the query string. I always get my global inbox. The following all return the same for me.
/2.1/me/inbox?site=stackoverflow /2.1/me/inbox?site=stackapps /2.1/me/inbox?site=windowsphone
Is this a bug? I don't think I'm doing anything silly...
