Today I was playing on junkertown and for some reason my entire team (myself included) all disconnected at the same time less than a minute in game. We were in a 6 stack and our leader did not pull us. Ultimately we lost the game because we did not have time to build ults or anything (and comms were understandably very cluttered). I was on the ps4 at the time and was curious if anyone else has experienced this happening. We all also have stable internet and even if we did not the probability of all of us getting disconnected at the same time is very low.
I once saw it happened to my enemy team. They were just as shocked as we were so no idea how that happened. It was on pc btw.
