There is a certain amount of time to select the contest finalists and winner. If that time expires, and the customer has not chosen finalists or a winner, then the contest goes on hold.
At the end of the qualifying round, you have four days to choose finalists. If the deadline expires before you choose finalists, the contest is put on hold.
If your contest is on hold you can resume it by doing the following:
Click 'Resume contest', as shown below. This will resume the contest for 24 hours.
If you resume the contest but do not make a decision within the 24 hour period, the competition will go back on hold.
You can resume 3 times, but after the third time it will lock. The contest will also lock if it is on hold for 14 days after the Review Period.
