Something has been up with PS5 (on Bungies end). I had no issues what so ever for the first month playing final shape, not even a single disconnect, but for the past 3 to 4 weeks, no exaggeration, I get disconnected from whatever activity I'm doing (usually GM's or Onslaught) 50% of the time possibly more.....never given the option to re-join session either, I'm just SOL.
I have tried, to no avail, everything that they recommend to resolve the issue. I know it's not on my end because my connection was flawless at launch for the first month. It also started on a Tuesday right after reset....if that's not a smoking gun I don't know what is.
