Known Battlefield 4 Issues and Next Steps (Updated: Mar 25)

I can't join games with 6 or more players in them.  Whenever I try, I get the "ERROR: Game disconnected: client closed down connection" error message.

I can play BF3 just fine, and I never had this problem during the beta.  I didn't buy BF4 until after the first patch, so I don't know if that patch broke something or not.

In any event.  I haven't seen anything about DICE being aware of, or attempting to fix the issue even though I've seen dozens of topics about it, so I figured I'd throw it in here.
