On my PC I can log in to my TV account but the TV client can't. I use there the same credentials. Do somebody know how to solve it?
I would modify my issue: The problem has solved without any intervention. I remember that I already faced this problem in the past and it solved spontaneously as now.
So my oppinion is that if somebody reinstalls the Windows (as me) and reinstalls the TV than sometimes the TV program can connect to the account only after a longer time - more days. I don't understand why it needs so long time. I would understand if it took half an hour. But 3 days...?
