It would be nice to include every subtitle language amzn or nf offers. Currently, you can select only 1 when you may want English & Spanish.
I don't know where you're looking but it's very possible to get multiple subtitle tracks. The problem however is when there are multiple variants of a language. Eg: En-US en-GB nl-NL nl-BE es-ES es-MX One language then overwrites another leaving you with 1 track instead of 2. That's a bug the staff is aware of and will hopefully issue a fix for soon.

Let me rephrase that. I'm aware you can select 1 subtitle but being able to include all in each download isn't possible.
"define" include? If you use the "embedded" option, each subtitle track will get added into the mp4. You select 5 subtitle tracks, you get 5 srt files or 5 tracks in the mp4
