Have users explicitly opt-in to Multi-Day QM instead of checking by default
Right now, when users navigate to the QM page for the first time, the "Invite me to multi-day games" box is checked by default. There's a bunch of pop-ups and yellow highlights in the view all at once, so it's only natural for a user who just wants a quick match to want to ignore all those and click "Play Now."
As a result, since QM's launch in 2017, players getting invited to random Multi-Day QMs has been a pain point.
Please leave that box unchecked by default so players can explicitly and deliberately opt in to MD QMs instead of getting surprise invites to games they didn't intend to join. This also makes those matches worse for opponents, who just have the matches expire with their opponents getting booted.
