Most of the time (not every time), I am asked to Activiate my Smart TV. I go to hbo.com/activate, follow the onstructions and enter the PIN. Within seconds my TV displays an error message "Please note it is not possible to sign in at this time. PLease try again later". This happens all the time lately and it's been happening for weeks. Any idea what the problem is here?? Extremely frustrating because I want to enjoy all the benefits of being a paid HBO subscriber! Thanks.
