When I’m logged in, I can only see four threads in this community. If I go to the community in a private window without being logged in, I can read all the threads. My user is on the same instance, so I should be able to see all threads - this can’t be a federation issue. What’s going wrong?
You probably have English disabled in your account settings. Make sure you at least have Undetermined and English selected to see the majority of english posts.
This was the solution, thanks!
