My oldish LG TV had an HBO Max app but it wasn't available in my area due to exclusivity agreements. In order to grab it, I had to change the region of my TV before going to the app store. This workaround is not required for the new app, I can just straight-up grab it. I wonder if rebranding with a new app allowed HBO to worm out of agreements like this?
