Seat Switching Broken for My Console?

So here’s the deal: I’ve been playing this for a while and loving the seat switching, used it on every vehicle with more than two seats. However, for the last two weeks it does not work all the time. I can always jump from warthog passenger to gun, but not any other moves. If I’m driver, it takes 3-5 tries to even dismount the vehicle. If I’m gunner, I cannot dismount the vehicle at all, I have to wait until I’m killed. None of the other vehicles work at all. I’ve tried re-installing the game, updating, full power-cycling the console, different button layouts. Anyone else having this issue?

As a further note, I think I am experiencing some kind of bug, because at the start of Warzone Firefight (this is where I’m seeing all these issues BTW) one grenade throw shows my inventory drop to 1, then quick to 0, with still only one grenade throw.
