just signed up to now TV, however having issues with my device. I got the now tv app on my Samsung smart tv however it won't let me accept cookies when asked to do so....
It’s for another device but maybe this thread might be if help.
You could try unplugging your TV for a few minutes.
You could also try unplugging your router for a few minutes.
As well as clearing the cache/data of the app just in case.https://www.pcwebopaedia.com/laptops/info/how-to-clear-cache-on-samsung-tv/
