Frustrating login problem with U-verse and Fire TV Cube apps
I've had terrible problems with ATT U-verse login from day 1, it seems the authentication protocol is just bad. My most recent issue is when trying to log into certain apps that call for auth through the Fire Cube, it doesn't not work. I login, it takes me back to the app but doesn't register as I've signed in. I try to log in with another app through Cube and I get the error with "fullfilling the request to 'https://zlp43257.vci.att.com/sps/authservice/authentication'... etc."
If I authorize through the browser with a code it's fine but this is extremely annoying because half of the apps make you do it through the Cube. This is making me highly consider changing ISPs.
I read someone else here that making a sub account then factory reset might work and it did not. I tried rebooting router and Cube. I cleared all app cache data as well.
