I noticed on Amazon when a video has more then 1 subtitle AS only downloads one, even if both are checked. Other programs will download both of them, it's an AS bug.
For me it downloads them just fine (tried en and nl to srt). Its when you do en-US (normal) and en-US (forced) that one track currently replaces the other' they're aware of that problem Sent from my Pixel 3 XL using Tapatalk
Yes it was English US and English CC it wound up being 1 file. Other programs I use do them both just labeled as English and English CC. Not a big deal if it's just that and multi languages all download OK.
