MM Live app. I use the MM alive app as the portal to access the tournament game I want to watch. Then it takes me to the HBO Max app. I signed up for the Disney+, Hulu, ESPN+, and Max bundle ($16.99/mo.).
So when I click on the game in the MM live app, it takes me to Max and I can watch the game there. Others may have a better way of doing it, but this is how I’ve been watching.
