@lukestokes . Great writeup, many of us are experiencing the same pain with Polo. I believe my failed deposit happened when I made the transfer while the Steem deposits were disabled at Poloniex. Seems to be no retry logic on that process so it just sits in @poloniex account until the support tickets are picked up. My ticket is 2 weeks and counting.
The one think I like about this community are people like you who help others by writing solutions based on your experiences.
MickD may be getting a lot more support tweets now!!!
