Hi mi7ch, there seem to be a significant delay in the world leader board updating, at least for some ranks such as bounty and hardest pistol whip. I am not sure if it happens on all rank, but I have seen it a few time for those two ranks. My hardest pw increase a day or so ago and it updated on the friends rank, but still has not updated on the world leader board. The world leader board does eventually update.
The Leaderboard does sometimes take a while to update, but everything seems to be working fine for me. Have you cleared your browser's cache, and done the normal troubleshooting steps?
hi mi7ch I run ccleaner a few times a day and have an alert set for browse updates. when I see it next ill ask my team mates if it is updating for them.
