Match making troubles

Is anyone else having trouble getting into matches from the start?

It use to be I select a mission, in about 10-15 seconds i’m in the pre game lobby, that usually fills up in 5-10 seconds than everyone is ready to go in anther 5-10.

Now half the time I get loading into a mission half way through, often with parts of my ammo or grenades missing or gone which is FRACKING annoying.

Or I if do get into a game lobby most of the time I still go in alone or with 1 other person even if I wait the full minute.
