I sent ETH to Snapshot's ICO address, I am yet to see ERC20 tokens in my wallet. Is this normal? How long do the SAP/ERC20 tokens take to show up once I send it to their address? Anyone else facing the same delay? 
It should be fine wait another few hurs if still not then ask again. You have to probably add the token with custom add to see it so you might already have them.
