Hello all. We can understand your frustration caused by the difficulty of either activating your existing account/subscription or initiating it for the first time. We provide support of adding the service itself and making sure it's coming through properly on your TV. For the online content, support would go through the MLB.TV Help Center or their support line.
If you purchased an MLB EXTRA INNINGS package, you can access MLB.TV online at MLB.TV or on your mobile or connected TV device using the MLB At Bat app.
If you have an MLB EXTRA INNINGS subscription, follow these steps to activate your MLB.TV account:
Go to https://secure.mlb.com/tv/activate/.
Select Xfinity as your provider.
Sign in using your Xfinity username and password.
Create a new MLB.com account or sign in with your existing account to link your Xfinity username and password with MLB.TV.
Start enjoying MLB EXTRA INNINGS and MLB.TV!
You only need to activate your subscription once during the season. However, you may need to sign in with your MLB.com account on each new device.
Once you have completed steps #1-3, you will be presented with an option to either sign in with an existing MLB.com account or create an MLB.com account. If you run into technical issues beyond the initial subscription for the service, please go here: https://www.mlb.com/live-stream-games/help-center/ in order to obtain further support. Since MLB owns the content, they also support their app and service that supplies it. Let us know what other specific questions you have. Most of them would need to go through MLB.TV support though.
