Hello ..today I sent 7.42 XMR from my Monero GUI Wallet on my Mac to the Poloniex Exchange. I have been waiting about 12 hours and the XMR is still not showing up in my Poloniex Wallet. From looking at the transaction history on my Monero GUI Wallet the transaction appears to have completed successfully ..the XMR is gone from my Monero GUI Wallet ..any assistance to help me find my lost 7.42 XMR would be most appreciated...
