Blurry Stream App

I've seen multiple posts on here regarding the same issue I'm experiencing with blurry Xfinity Stream resolution while any and all other apps are beautiful, therefore not a bandwidth problem. Any potential solution seem to involve sending a direct message to xfinity support via this forum. However, according to other previous threads, the direct message feature isn't available to anyone who hasn't posted anything before, lol. So can I please have my direct message feature enabled, and/or my picture resolution issues fixed? Too many hoops to jump through
