Recently bought the Roku SKU# 3821r and now find, one cannot stream SlingTV or Philo directly by an app..
The website for Roku does not list this model - at least by SKU number, nor is the same packaging currently shown - nor are any SKU numbers listed on any products - only names. The website seems to avoid any "excluded apps" mentioned on the devices. That is until after one buys the product and them won't let me now download, with my account, to my device.
