The shows on it are great, but the app experience is unfortunately highly unreliable. Very often I encounter a 905 error or some other error code when trying to screencast from the app. Sometimes restarting the app helps sometimes not at all. It's really unpredictable and leads to 10-15 min of restarting and trying different things until it sometimes works. Sometimes even after 15 minutes it doesn't and then we decide to go for Netflix or something else. HBO please fix this!
