The page at https://fedia.io/sub is called the “subscribed” page, and shows threads from various different “magazines”.

Fair enough, but isn’t it supposed to only show ones from groups I’ve subscribed to? Does my subscriptions have any effect on that page at all? Is it just subscribed instances maybe?

Is it supposed to be like that? If the latter, is there in fact a page which shows only threads/blogs etc. from just groups I have subscribed to?
