lately transactions it feels long, try to wait a while longer. maybe it will take place in a few minutes, or hours, but I believe, that transaction must have run immediately. I also never experienced anything like this, but after a few hours, I have been in the confirmation transaction.
It is all because you probably didn't adjust your fee accordingly. If you pay current standard 120 satoshi per byte your transaction will be confirmed very quickly.
There is no really any magic behind that other that miners are becoming more greedy.
