Is anyone else experiencing issues with group post notifications not appearing correctly on Facebook?

Not visa related but group related. Im getting notifications of posts but they're not coming in at the top of the posts. Im having to search through about 3 days of posts to find the new ones. Not sure if it's a group or FB glitch but just thought I'd let the Admins know. It's been happening for over a day now, anyone else having the same problem? Not a huge issue just a heads up!
