Another BBM Question: Notifications, but no active chats

It's the strangest thing. I get notifications that someone has sent me a message but I don't have a new chat pop up, nor does it show that someone wants to add me. The worst part is that I know some of them are from people in my contact list because they'll tell me I'm not reading their messages.

They're not group chat notifications, because that's a different icon and it seems to be working fine. I also don't have anyone blocked.

What could it be? :confused:

Anyone? Beuler? Beuler...?

Things to try:

1. Pull your battery.
2. Delete those affected people from your BBM Contacts list and re-add them.
3. Restore your BBM contacts from back-up.
4. Delete BBM, reboot, and re-download it.
5. Wipe and reload your OS.
