Netflix has managed to annoy a good number of its users with an announcement about an upcoming update to its Windows 11 (and Windows 10) app: support for adverts and live events will be added, but the ability to download content is being taken away.
Netflix must realize that it's a huge frustration for people who relied on offline downloads to watch content without internet access: on planes, trains, and campsites, and anywhere else where Wi-Fi is unavailable or unreliable.
There's a small chance that Netflix will change its mind if it gets enough complaints, but the streaming service seems determined to add as many money-making features as possible, while taking away genuinely useful ones.
How does it find subs if no one's created the sub file? Does it auto translate them from the original language?
No*. You can add providers which will automatically check for and download (all of) the available subtitles and it can automatically check for new and updated ones so that you don't need to. It can also do synchronization and modifications like fixing uppercase and OCR. It greatly reduces the amount of work that you have to do.
*I just checked the OpenSubtitles.com provider and it has an option for AI translated subtitles in search results.
