Hi, I just did some investigating.
It appears you don't get the 'My Feeds' or any of the feeds options until you actually subscribe to a feed in the first place. I'll bring it up with the devs, as I don't know if that's working as intended.
Also amazing feed, I've subbed ❤️
Edit: You can find the initial 'feeds' page under the Communities section, which when subbing will show up under Explore section.
