[SOLVED]: The issue was caused by having "Show read posts" unticked in Settings. This will hide your own posts from you!
I recently made a post^[1]^ to this community about a bug that I experienced and reported.
The post does not appear in the New feed for /c/lemmy_support nor does it appear in my user profile under Posts ^[2]^.
However the post does have 3 replies (from users on multiple different instances) which means that other users can see it across the fediverse, so it's not a federation issue. (Also, my account and the community are both hosted on the same instance - lemmy.ml).
I was not subscribed to /c/lemmy_support at the time I made that post, but I am subscribed now to see if that affects my visibility of this post.
Is this a bug, or am I misunderstanding how lemmy works?
Interestingly, if I view my profile while logged out, it does show the posts that I made, but when logged in it shows zero posts in my profile.

Yes, that was it! Thank you!
