Congestion has subsided on Ethereum network, so we've re-enabled purchasing of ETH with other cryptocurrencies, including, of course, Steem and Steem-backed Dollars.
We've also re-processed all existing transactions where users purchased ETH but the ETH didn't arrive because the transactions failed to get incorporated into the Ethereum blockchain due to the congestion. If you were expecting ETH from us but had not yet received it, please check your Ethereum wallet and verify it has arrived.
