Maybe I didn't make myself clear: I think XDA Labs works as expected in my opinion, it's the button on the forum desktop web pages that always brings me to the thread last message and not to my actual last read message.
If I open a thread using XDA labs after pressing the "view first unread" button on the web site, XDA Labs points to the last message too but it makes sense because "view first unread" brought me to the last message a minute before, therefore such message became my actual last read message.
