Probably not helpful or not what you'll want to hear, maybe I gave up too early but I had to purchase a live tv streaming package on like Hulu, Tubi, YouTube, Sling, Paramount Plus. There are many options unfortunately they all cost around $50-$70 per month but hey at least I get to watch football 😞
For me the NFL app continues to crash, lockup, or simply display error403. Odd thing is that I can watch any game streamed on it so long as I am on my phone- via Verizon but switch over to the big screen via my cable connection Cox and nothing but problems. yes I've contacted Cox tech support, they say that they do not trouble shoot 3rd party devices.
