My NFL App was working fine until my iPhone 6s upgraded to a new OS. Now when I select a game I'm sent to select a TV provider. I select Verizon, which sends me to FIOS to log in. I used MyVerizon credentials and it's states either of those are wrong...even though I used them to log into MyVerizon.
FIOS doesn't recognize any of my account information. If I go register then it states I'm already registered.
The NFL App worked fine before this OS upgrade. Worked fine for a couple years and 5 days ago. What is going on?
