I've attached a screenshot of what I see when I go to my profile. Maybe I'm just blind, but I can't find a "subscribed" list for magazines. There's the one for threads, but posts from more obscure communities are difficult to navigate to.
Edit: I found it. I need to click on the rightward-arrow next to "Followers" under my banner in order to reveal "Subscribed".
Thank you for pointing me in the right direction.
