I can't believe it has taken until the end of 2019 to get here, but we're nearly here -- in a world where YouTube allows video downloads at 1080p, at least with YouTube Premium.
Android Police were the ones to first spot the update, with multiple sources then confirming that the 1080p video download feature will be coming out to "most Premium markets" soon, as well as more features in the near future.
The limitation has been at 720p for a while, but the uprgade to 1080p is a big one (and hopefully 4K doesn't take this long). You'll need to have a YouTube Premium subscription in order to get 1080p downloads, but it should be enough... right? Or do you think it should be all resolutions, right now?
