Users are reporting issues with the unread functionality, whereby when clicking the thread title (eg. /threads/title.numeric/unread ) from the thread list, they are not taken to the last unread post, but instead to earlier posts. Some example user reports ...
Same here. I marked all forums read earlier today, just opened this thread and it took me to post #21. Read the remaining posts, went back to "Watched Threads", this thread still shows as unread and opening it still takes me to #21.
viewing new posts in watched threads no longer marks them as read for me
I'm also finding that threads I'm watching with new posts aren't showing up in the "Watched Threads" list.
I'm not familiar with how the functionality/mechanics of unread posts operates with XF, whether it's a database record, user cookie, webserver session variable, or combinations of these etc.
How does one start to investigate and diagnose this issue?
