Thanks - Glad it is not just me. I'm in Eastern Upstate NY.
From the website below, I see MANY people all over the US are having problems. Roku, Spectrum apps, live TV, etc.
Can't log on to watch live tv here in So Cal too. Usually I don't even have to sign in, but today when I tried I got a box that said my info didn't match their records.
Tried logging in with Chrome and Edge. Neither one worked.
Finally, I can watch TV with https://watch.spectrum.net/livetv .
I hope Spectrum fixes their problem for everyone else.
Their main website is horrendous. I wish at the very least they would post a prominent notice on their home page that they are experiencing problems (Like way back in the 1960's, TV stations would display "Please do not adjust your set. We are experiencing technical difficulties"). Unfortuately, if Spectrum displayed a notice, it would be displayed for several months.
