I seem only to be able to watch all MLB games on my cell phone, but not my TV or tablet. Is this right? I can watch only one game today on the season's opening day on my TV and tablet.
You should be able to watch all the great goings-on on your phone, tablet, and with many TV options. MLB.TV That page shows you can use Roku, Android TV, AppleTV, and more. You want to make sure that you have the MLB TV app installed on whatever device you are trying to watch on and it is signed in with the same username and password that you used to redeem the MLB TV offer.
These are the starting points, so you have probably already done those. You may also want to review the blackout restrictions for your area to double check that it is not reducing the content you see.
If it is getting all of the content on your phone, then I am confident that your subscription is active. It would be helpful to know what error you are getting when you try to watch the other games that you are interested in.
