Can't enter a game; endless matchmaking

This has been happening to me since Friday and is really REALLY messing up the way I normally play.

I have a post in the bug reports about this very issue here:  Never-ending queuing with fill teammates unchecked 

There's at least one PS4 player experiencing something similar as well.

I've already confirmed that -for me- this is something outside of standard connectivity issues.  I tried different regions (first thing I did when I couldn't get into a game).  I tried on my desktop and my laptop, along with a round of verifying the game files in origin.

The real kicker is this though:  my two kids have their own Apex Legends accounts, I can log out of origin and log in as one of them and everything works FINE - they can uncheck "fill teammates" and get into a game with no problem.  If I log back into my account the problem returns.   The fact that other origin accounts on the same computer/install aren't seeing the problem should eliminate most user-side sources of the issue (install corruption, driver issues, network connectivity issues etc).

It works consistently on some accounts.  It's completely broken on another.  I still can't figure out what the difference actually is.
