Disconnects - Your Fireteam Has Changed

So I keep getting issues where I lag out in Warzone (separate issue), so I switch to Arena and tend to experience no disconnects. However, I keep getting kicked from games and it says “Your Fireteam Has Changed.”

In Warzone, I know I’m about to lag out because everyone starts running in a straight line, but this Fireteam issue can’t be lag as it just instantly kicks me. The only other posts I’ve see about this issue are on Reddit. Not sure why they wouldn’t post here.

I get the left fireteam when playing solo. No lag issues.

i get the same problem almost every other game on both arena and warzone. I’ve lost so much CSR points on arena because of it

i’ve just started getting this problem now, havbe any of you guys found a way around it?
