For example, my user/profile is based in beehaw, but I subscribed to this community on lemmy.ml. When I view this community, it says I’m joined. But in my list of subscriptions (in both Jerboa and the Beehaw website), it only shows my local (Beehaw) subscriptions.

Is there a list of “external” subscriptions anywhere?

Also, is it possible to subscribe to all communities on an instance? Lemmy is small enough that it’d be easier to just selectively unsubscribe, I think.
