Hmm, when it comes to menu it’s usually someone radically moving the selection. I could see someone just being a tool and just sitting there but it’s hard to tell because they could be updated their shadow.
Nonetheless, I will leave if someone is just sitting there for too long.
In that case, I would say it’s someone trolling. Are they a lower rank? Not to pick on lower ranks or anything but I usually notice Bronze players desperate for a win. When they win by either sheer luck or a lack of effort they will usually sit in the selection menu, radically move the selections or leave. Makes 'em feel better I suppose.
If I ever do this, it’s generally cause I’m not on mic and I’m about to shoot you a “GG/Hi!/Gotta go” message, but by the time the gamer card has loaded up and I’m compiling the message, a lot of the time my opponent has already left (I’m not talking about a long message either, usually just one sentence). The Xbox app loading gamer cards or chat just seems to take forever on PC, at the very least it’s around 30 seconds, so maybe it could be that.
Also in response to moving the selections, are you sure people aren’t just trying to play “The Instinct” with the selection music queues in perfect timing? Cause I do that sometimes, fun Easter egg is fun.
if they wanna troll by making me wait, ill troll em back by making them wait for me. ill get off the game, and go lie down for a bit looking at my phone to see who is coming over, or ill go downstairs and do a couple chores. if i return and they’re still there waiting for me to leave i lol, and play zelda on my switch haha
