The Boys Subtitles

Does anyone know of a way to turn on subtitles for only non English speaking parts? I'm watching it through a Chromecast from the Prime Video app on Android. We just watched episode 2 and the first conversation they had in Japanese and sign language I just assumed we weren't supposed to know what they were saying, but then after that went on that long and they went into another scene we rewound it and watched it with the subtitles fully on. I couldn't even find a way to get English without the full CC where it does music notes and (girl crying) and all that shit. I feel like I must be missing something but I stared at it for 20 minutes and came up empty. I really don't want to have to sit there and pause and mess with subtitle settings every time there might be a foreign language spoken cause it seems like there's going to be a lot of it.
Apologies if this has already been discussed in the spoiler threads but we're behind so I didn't want to venture into those yet.

That's interesting, you would think it would be the same then. It's only recently that I was even able to use the Chromecast with the prime video app (they insisted you buy a firestick which, lol) so there could be some residual effects of the Amazon/Google spat affecting features like this. I found one other person complaining about this on the Amazon forums and the response from their staff was "we will forward your feedback to the video team" so it's looking like I'm just going to have to mess with settings a bunch of times and deal with the (door knocking) (footstep) (door opening) stuff. Oh well.
Looks like this is the case, bummer.
This was episode 2 and 3 for me but yea, episode 3 they were where you'd expect. I haven't fully caught up but hopefully it's just the one episode that has this problem.
