@beyond9thousand For example when I look at my recent followers follow list, and it says 30 posts I can only see those that talk to the specific server/instance I've joined. In my case, mastodon.online. So it shows like 2 posts out of the total of 30. It is the same across all activity of a specific user.
Fortunately there is a way to see all posts/follows/followers by just opening up the profile on the instance that user is part of. 2/3
