Foxnow no longer part of tv subscription or FBC Fox

I am now getting an error “FBC Fox is no longer available. Please contact your TV provider AT&T for more information.” This is referring to the Foxnow app. 

I can watch fox on my tv and have used the app on my phone and fire stick for years. I haven’t changed my subscription so not sure why it stopped working Sunday. 

I have uninstalled and reinstalled app. Fox states this is an ATT issue. 

edit: I have att U-verse for my tv. I just use the Foxnow app to watch shows in my other room on my fire stick. 

help.
