I haven't logged into used Facebook for months, probably well over a year but several recent notifications dated in the last month have been marked as seen. I'm worried that smeone has hacked my account but I don't know of any other activity. Does anyone know of any other reason for this - could there be a bug in facebook for instance? Anyone else had the same issue.?
Thanks.
I've noticed lately (at least via the Android app version) that Facebook will automatically mark some of the notifications as Read. I haven't really investigated the exact reason why yet, but it seems to happen AS I open the notifications menu. It'll show (for example) the number 30 on the notification button, then I click it, and before my eyes, a bunchof them will go from the "unread" blue background to the "read" white background. I'm pretty sure it's just marking notifications of other people who have "Liked" a comment I made, but again, I haven't looked too deeply into it.
Is this the same thing happening to you? Either way, it can never hurt to do a fresh password change anyway.
