Out of all the devices I have this app on only 1 consistently plays. I still experience a brief loading wait on that device. my phone is hit or miss. mostly miss. it won't load more than half the time and when it does there is a longer wait for whatever I'm watching. other than those 2 I can't get it on any other smart t.v or tab. HBO y'all need to get on this. Obviously, you all are aware of these issues. There are plenty of reviews saying the exact same thing. 15$ a month. it's not worth it
