There's no option to start a live game in MLB TV app

I just installed the Apple TV 2021 and now on the new MLB TV app, there is no option to start a live game from the beginning or even to rewind what you are watching. This is an abrupt loss of one of the most basic features of a streaming app. Is anyone else experiencing this problem? Is this a known issue? I called MLB TV and they recorded my issue but seemed totally unaware of what I was talking about, and told me to try reporting it to Apple. How do I even do that? When I google "MLB TV app help," I get MLB results not Apple results.
