Some managers may think that this feature is good because manager can adjust the match time in case there is urgent matter to handle. But using this feature affect the other party in an unfair manner. I like the old system that any such change should be made at least 24 hours before the match start time.
Hey cook, are you sure about that ?
I read another time about your issue but I still can't do that (to set my match before the schedule time).
Maybe there is something wrong with your account/region/server, don't know what.
I think you must start a thread and ask if someone else has the same problem

* If your opponent can do that, it means that also you can set the match before 24 hours. Is it that way ?
