Samsung smart tv Apple tv app sign in issues

Hey all,

i recently bought a new samsung tv with the apple tv app on it. Initially i could log in with no issues so i bought and watched some movies. For a few days now however i can no longer sign in. I tried resetting the app, re-downloading it, and i also removed the samsung tv from my apple id profile so that i could do a clean log in with a new auth. code.

it always gets stuck on the sign in with the rotating waiting icon but never moves beyond that. Also using the option with using a mobile device to log in results in that waiting screen and never going to the screen with the QR code.

does anyone have any ideas? Thanks!!
