That's is the problem with this site. Everyone expect instant payments for these trusted sites but since quite long time fortunejack is not sending payments instantly. They always take almost 24 hours and many times we need to remind their stuff about withdrawals not received.
From the first time until now i've been playing on fortunejack, all of my withdrawals never pending for 24 hours, just took some minutes. Did you ever tried to withdraw from fortunejack before?
Yes, I had this issue recently, and they took almost one day to send my withdrawal after contacting their support team. It was pending for their approval to send and don't know the exact reason why they keep withdrawals so long to approve. But if you contact them they will surely send your money.
