Cannot log into Smart Home Manager
Have had AT&T Fiber 500 for about 3 weeks now, I am still not able to log into the Smart Home Manager app. Every time I try it tells me I need to have AT&T internet. I do. I get an error code of 403.400. Called the local store but they were of limited help. Called customer service last week and they gave me a different username that I had signed up with in the store. That didn’t work. They were supposed to call me back but never did. Frustrating to say the least.
