Cant get to log in to apple tv on my LG TV

it works fine on my computer, on my cellphone. Try to log in into my LG TV using QR code, entering code into activate.apple.com and manually signing in using my remote. None of them worked. Always tells me: YHou were signed out of Apple TV app. Enter the password for apple ID ***@email.com to sign in again. Gives me to options to sign in or cancel. Press sign in and leads me again to the screen were the QR code/ link / or sign in on this tv. Do it all over again same results. Again it I can access perfectly fine on any other device, tried uninstalling the app and installing it again on my TV with no success. Searched an answer saw a lot of people with this problem but no solutions, does anybody know what to do? Just suscribed to apple tv and its a bummer i cant access it on my tv. REALLY FRUSTRATING.
