is the update section lagging a bit?

Is it like, Ur not getting update notifications on stories that you're reading, it happened to me too sometimes ago multiple stories were updating n i wasn't getting any notifications, but later it got batter on its own? I think.

It refreshes every 12 h or so

It's the same stories showing up every time I refresh ;-;
The amount of time is going up, but the stories are staying the same
