Https 'M Youtube Com Feed Subscriptions. When you subscribe to a channel, you’ll automatically get personalized notifications. Its back now, idk why but it just popped back into existence after watching a couple.
It has an icon that resembles a series of rectangles with a white triangle in the middle stack on top of each other. Don’t know how to get all the subscriptions at the same time, but i don’t wanna be reliant on subscribing to a channel in the first place. For example, a section could feature a channel's latest uploads, most popular uploads, or videos from one or more playlists.
