Horrible! I've had this app for over a year and rarely use it because all it does is constantly buffer and freeze when trying to watch anything. I just recently came back after a year, to watch season 2 of Raised by Wolves, but the buffering is so bad, I can't even watch the show. How embarrassing that a company like HBO can't figure out how to make a functioning app like Netflix or Prime, after over a year of offering it to the public. They need a serious overhaul of this app!!!
