Description

Downloading youtube subscriptions seems to have stopped working just recently. Youtube-dl simply reports that there are no videos available, which is not true, as browsing to the URL (for me) shows a bunch of videos.

To reproduce, export all browser cookies (I haven't tried just exporting youtube domain cookies), and try to download https://www.youtube.com/feed/subscriptions. Instead of downloading the videos in the subscriptions, it should just say there are 0 videos available.

I will also note that this exact URL and this exact config has worked a few days prior. Ignoring config (i.e. adding --ignore-config) doesn't help.

Just want to add my own log to the above, started happening on the same day as the 2020.06.16 release, not saying it is this release, just that it started the same day.
