Withdraw from Poloniex via TRON network is "processing" after more than half a day

I have a withdraw that is still "processing" after more than half a day. I was trying to withdraw USDT on the TRON network. I had done this many times before, including just several days prior. This is the first time that a withdraw has taken this long--it usually takes only a few minutes.

I reached out to customer support and they told me that it needs to be reviewed and "manually approved".

What's the likelihood that I'll actually ever get access to my funds? How long will it probably take?

Very unfortunate that this is the customer experience that Poloniex confers on its clients.

Hoping for the best but expecting the worst.
