Forum "not syncing"?

[lfom]

Hi. Again, I don't know if I can ask it here but I couldn't find a better place... Since a few days ago, it seems that posts that I read in one computer using a browser aren't 'marked as read' when I open the forum in another computer. The same happens when using Tapatalk custom app. I think it worked before... Is it a known bug? Any way to fix it?

TIA

Update: even while using the same computer, If I visit a post and then use the "What's New" link at the top of the page, the post I've just opened is listed as "unread". I am sure it worked fine until a few days ago. It happens with different computer and with Tapatalk also. JFYI.
