FS1 & FS2 came back for me today. But my local FOX (WTTG) disappeared:
https://api3.fox.com/v2.0/liveplayer/5836e01f3f93d90001ab6627?geoLatitude=(mylocation)&geoLongitude=-(mylocation)&epgListingId=WTTG-program-WTTG-1739966400000: 403 Forbidden: "{"@context":"http://www.w3.org/ns/hydra/context.jsonld","@type":"Error","n…":"Invalid AccessToken Key Id","detail":"Key Id not found or supported"}\n"
I tried unchecking and re-checking "Local Networks via TV Everywhere" and updating to the latest pre-release... no joy.
