Description of issue:
Trying to share url of subdomain but twitter card strips subdomain from the link. All twitter meta tags are correct according to troubleshooting docs. Robot.txt is allowing data to be read as proved by the posts showing up all of the data minus the subdomain. Twitter card validator displays properly. When sharing on twitter the subdomain is stripped from the url. This happens inconsistently. Looks like when you are logged into twitter the subdomain gets removed. When you are not logged in the subdomain is shown.
URL affected (must be public):
