I have tried deleting the app data, then I tried completely uninstalling and re-installing but every time I try to open the app it says "Something went wrong. Please try to access Peacock from a more secure device."
The app had been working fine until now.
I have the same issue with my TCL TV with Google TV. Worked fine last night.
Same thing on my X95j. It was working fine up until yesterday.
Updated the software on my TV and it works. Still hate the Bravia Android.
It's working fine now this morning. They must have fixed it on their end.
I was able to get it working last night on my x950g by casting from my phone. I have problems on my GCCwGTV every once in a while, but when I switch off the adblocking DNS, it usually works (but then I have to watch commercials). That did not help w/ the TV last night.
your network has been compromised
Same issue on chromecast w google tv and my nvidia shield.
