Behind, for sure, it takes me to things from a month ago. But sometimes it takes me to things I didn't see via email.

I usually open the link from the email to read and reply. The “bell” I rarely use. I find it is too general and behind.

Thanks

oh, and the unread pnes are usually shaded gray and the ones that you read are white.

The bell will show you all notifications, new and old until you delete the old. Believe me, I have to delete the old ones every day after I read them, since I get many a day. You can go into the setting to set how you want to be notified and I believe how many a day (at least it used to, not sure now since they updated the site).
