Fully agreed, and thanks for taking the time to respond to my post. I don't remember how I did it. I think I wanted to subscribe to the magazin kbin and ended up subscribing to the whole domain, too (the timing fits).
While the mistake is certainly on my part, from a usability point of view it would have helped if the two separate subscription lists profile>subscriptions (some features) and settings>subscriptions (all features) would be consolidated into one single list.
Solution: I had somehow subscribed to the DOMAIN kbin.social by mistake. I didn’t even know this was possible. This took a long time figuring out because domain subscriptions can only be seen from the settings page, not from the public facing profile page.
I think I was able to narrow it down and it feels like a bug.
The subscribed threads view has an additional filter option: all, links, articles, photos, videos. When choosing links or videos my subscriptions are respected. When choosing any of the other three filters my subscriptions are not respected.
Thanks for the response. I don’t have anything out of the ordinary, I think (certainly no custom scripts). I‘m a casual user with a regular Chrome browser in default settings.
It seems to be my account. I have the same issue when logging in on my phone.
