Horizon Life Lobbies since Oct 10 Update

Has anyone else noticed that since the Oct 10 update they will join a Horizon Life lobby and it will start with usually around 35-40 players and then within about 15 minutes it will dwindle down to sometimes as low as less than 10 and never replenish itself with new players? It can really stink because if you only get say 1 in 10 players to do the #Forzathon Live events you only end up with 2 or worse sometimes yourself doing the #Forzathons alone. Is anyone else noticing this?
