MLB app no longer available on third-generation Apple TV - MacRumors

The MLB app now requires an Apple TV HD or Apple TV 4K (i.e. 4th generation or later).

I have the same issue. I have had the MLB app for three seasons now and have paid for it, but it does not appear anymore on the appletv list of apps on my TV, just my phone, so I know I am signed up. MLB says it's not their fault that I have to add an app. Nobody at Apple will answer this question or even talk to me. getting frustrated.
