[FORUM] fully read topics still marked as unread in latest tab

in the latest tab, topics that contain posts u didnt read r highlighted.

however when i read a new post of a topic and then go back to latest tab its still highlighted.
when i read the post i have to scroll all the way to the very bottom of the page for it to consider the post as read.
the bottom of the page consists of the suggested topics section. so i always have to scroll all the way down till the post is out of view.

having to scroll all the way down every new post for their topics to be marked as read is quite annoying.
i use the latest tab primarily to check out the forum.

Is this mainly on PC or mobile? Or both?

i can only use the forum on pc. my phone is too old for the new os update and my os is too old for a new browser update x.x
