Who else finds this annoying.., after you've checked all your wall posts, likes, Friends Requests etc etc within the Facebook for Playbook app I always have to login separately into my BB phone to get rid of these messages manually.
It doesn't stop there, once you login to Facebook on a normal Desktop PC you still have to get rid of all these messages that were read like a month ago.
This is a functionality that I've been missing for a while and since they are updating the Facebook app for the PB and BB phones allot lately I think this is a standard functionality that should be build within the apps.
Check your messages in one of the devices and sync with the server that purges them from all other devices/systems
