We have several large threads in my forum and I use the “posts in topic” function quite frequently to look at individuals separately.
However, starting today (April 2), after clicking on it and attempting to scroll down through the posts, it stops and reverts back to ALL posts in topic.
I did check with other users and am not the only one this is happening to.
EDIT: Just tested it here on one of the larger threads and the same thing happened.
