Unable to sign in with my provider on streaming apps (for Firestick)
I am incapable of logging into certain apps (ESPN, USA Network, HBO GO, Adult Swim, etc.) that use single sign-on and have me provide my Xfinity/Comcast information using the app to sign in.
When attempting to sign in, I am brought to the "Choose Provider" page, and select Xfinity. Whether the username is remembered or not (if not I type it in), I type in my password and then press "Sign In". A yellow progress bar appears at the bottom and it seems like it is loading a new page, but then it brings me back to the "Choose Provider" page. This results in a constant cycle of trying to login and being returned to the login page to login. I have attempted this with another Xfinity/Comcast account as well, and the exact same problems arise.
This is different from other streaming apps (Ex. TNT, TBS, Showtime, etc.) that provide you with a verification code, and require you to you login elsewhere (Ex. https://www.tntdrama.com/activate/firetv). With these apps, there are no problems and I am signed into my streaming apps to view the content I pay for.
It appears that there is a problem with Xfinity's authentication process when utilizing the apps to sign me in. Any help would be appreciated!
