did you manage to withdraw any BTC from Poloniex?
They seem to be automatically deferring any withdrawal requests to "Awaiting Approval"
actually i didn't moved any BTC today, i could try later to move some
in the past i didn't had problem (i just had to confirm a link on an email polo send when you want to withdraw)

Update:
just tried to withdraw 0.1 btc, i just had to enter my 2FA 6 digits, confirm the email and now i'm wating the standard bitcoin confirmation time (i see the tx listed as pending in polo transaction history)
