A: Hello,

Thanks for your interest and questions. Please find the answers below:

1. For multiple audio tracks, it is not well supported. We may support it in the next major update.
2. You can download one subtitle per time. If you try multiple times, you can download all subtitles one by one. We support downloading original, auto-generated, and translated subtitles. You can easily download it as a file, or embed or burn it to the video. We have a good support to subtitle downloading.

Thanks and let me know if you have more questions. I am happy to help.
