I'll blame my VPN for now... will be trying a different one... but I chose a few different servers around the country last night to make espn app think I was out of market... tried Miami, Chicago, Seattle, Dallas, etc..
In each situation, the ESPN app itself told me in its error message that it detected I was using a VPN and it was not permitted. I had to turn off the VPN to use the ESPN app..
So it could be that whatever way my VPN was anonymozing itself or presenting it as being in a different location is being detected by the app...
Hulu worked for me last night but that isn't a guarantee long term..
