I know this "thread" is from 11 months ago. But I was actually attempting to arbitrage from one Exchange to Polo via SBD and it's been more than 4 hours since my first test amount has been received. Have the confirmation times increased that significantly in 11 months? Or is this related to Polo having issues with SBD/STEEM wallets? I saw this message on there yesterday, but it wasn't there today so I thought I would give it a shot...
