I tried to fire up the ball game last night on my new Mi Box, and the app won't present me with the International feed, requiring me to log in via Fox to view the "National" feed instead.
I'm not using a DNS service or anything, because I haven't needed it all post-season; my Apple TV, Nexus 5 and Smart TVs all present me with the International feed as they are supposed to, since I'm not in the USA.
Has anyone found a workaround for this (aside from using the Kodi addon, which is what I ended up doing last night)?
Haven't found a workaround but the same thing happen to me. I'm in the US and I do use a a DNS service to get around the blackouts. For some reason throughout the playoffs I would sometimes get that message but when I tried it on my PS4 it always worked fine. Not sure what is causing it but your not the only one.
