Some threads that are visible when logged out become invisible when logged in. This seems to apply to all magazines and all instances - I am not completely blocked from an instance or a magazine, they just don't show all the threads. This seemingly started relatively recently, because I now cannot open a thread that I commented on 2 days ago. However there is some possibility that it happened in the past and I just did not notice, I only go here once in a blue moon.
When I open one of the threads using a direct link, the body of the post itself is shown, it shows the correct number of comments, but the field where comments should load says "No comments".
Example threads that I don't see:
Example 1 (the one that I commented on)
Example 2
Example 3
Additionally, and I have no idea if this is related, I cannot send direct messages to anyone outside of kbin.social, the "Send message" link in their profile just sends me to a 403 forbidden page. I have no idea whether this is related or whether it's just an unfinished feature (in that case ignore this) - I only noticed now, after I wanted to message somebody that unfortunately I can no longer reply to their thread.
I am quite new to Lemmy and I don't yet understand specifics like this, so that may well have been it. Thanks.
