I have a 4K Firestick. When I add a new application like ESPN or ABC I try to link to my TV provider to get access to the application. I can get to the Select Provider screen and I click on my TV provider and it gives me a white screen and goes nowhere. At another location I have Comcast WiFi and when these same two apps asks me to sign into my provider it goes to the sign in page for my TV provider.
Any thoughts on how to correct the problem?
