Unfortunately the same problem as most other streaming apps these days. It seems like you spent billions of dollars on content and maybe about $15 for some 22-year old IT kid to develop your app. If the episodes load at all, HBO max doesn't have the usual player that most streaming apps do when you cast it. So there's no way to turn on subtitles, or even pause it. You can either play it endlessly or disconnect completely, your choice! I miss when Netflix just had everything...
