Why does SBS (Australia) stop working?
SBS shares some video services with overseas sites that we unblock, like CBS and FOX.
So, by default, SBS thinks you're located in the USA.
You can change your location for these services if you log into this page https://www.getflix.com.au/manage/regions and change the region for "Channel Group A" to Australia. SBS will work again!
Of course, while this is set to Australia, overseas sites that use the same video services, such as CBS, FOX, etc won't work. You can change between the United States and Australia as often as you like.
