Is it just me who can't see unread posts?

Click on the burger to see that there are x unread, navigate to see the threads they're in, but then encounter problems.

In a popular thread, it is a guessing game to see where the unread posts may be. 
Page 8 or 9 of the GNE latest? When I take a punt at page 9, there's then no indication of what is new or not other than to go through and look at the date of posting. 
Nothing to highlight what is new or what isn't. Nothing to differentiate between something posted two weeks ago or 2 minutes ago.
