I have a website at the URL
www.example.com, and I have another page at the URL
hello.example.com/cornerstone which uses the same tracking ID. In my default analytics view I can only view data related to
www.example.com, even though I tried creating a segment and filter by page/page title still I don't get to see the data of my subdomain.
Can someone explain me how to filter data by URL and view data related to all the subdomains/pages which uses the same tracking ID? (I don't want to use another property for the subdomain.)
