Hello @bamjeff I happened to have transferred some yesterday, so still remember the process. The transfer took maybe an hour or less. Did you go to your wallet, then Permission, and then used the last key (which says MEMO) starting with STM? If yes, then I don't see anything wrong and maybe it's a delay on the part of Poloniex. If you put any other key, then there might be an issue, and unfortunately, I'm not experienced enough to tell you what if anything could be done to reverse the transaction (probably in that case I'd make a ticket to Poloniex). Hope all ends well!
