An opened invite waits for you
An invite link you open no longer hides your other teams; it waits on the start page. After you are let in, the team opens within seconds.
Opening an invite link used to cover every Team page until you answered it, so you could not check a channel first. Now the invite waits on the start page, under Start or join a team, while you look around.
While you watch your join request wait, Bandicot now checks every few seconds, so you land in the new team almost as soon as you are let in instead of up to 15 seconds later.
