Can confirm that this is still happening. Really hoping for a patch on monday. I didn't go into gamedev specifically because I wanted to avoid crunching, so I totally get not shipping anything on the weekend lol.
Since I'm bored, I'll speculate that due to how the timing is always similar, both on the first disconnect and the latter periodic ones, I would guess its some sort of token expiration issue with auth servers. No idea why it isn't happening to more people though and I don't have the stones to try debugging it since I'm pretty sure Javelin would obliterate me if I tried capturing traffic lmao.
