Hey,
The conversion of coins in blockchain.info is powered by a third party called shapeshift and I just checked their site. Apparently, Transactions may be delayed for hours as both the bitcoin and ethereum networks are congested.

The Ethereum and Bitcoin networks are currently experiencing significant congestion. Transactions may be delayed for hours.
So your funds will probably show up after a few hours but since blockchain.info's support can be slower than turtles, I suggest to contact them now in case something happens like waiting for the exchange process for days. *Please note that the conversion/exchange process will only start once they've received your deposit and as you said, it only confirmed today right? So technically you haven't waited for days.
