I requested an instant withdrawal of .00064861 BTC on July 22, exactly 7 days ago to the hour. It is still pending, they have not sent it.

Yesterday, a small yellow ! in a circle appeared next to word Pending, and if I click it, says

"Your payout requests are waiting to be manually reviewed. This process might take up to 24 hours."

It has of course now been more than 24 hours since that symbol appeared.

I will update if and when they send it.

My userid is 5 digits, it's a very old account, have never had issues before.
