I saw in their reddit AMA this info:

For winners of the lotteries when doing KYC there is a option if they want to participate in round 1 only or both rounds 1 and 2. Round 2 KYC will only start after round 1 of the sale.

Round 2 KYC starts on 21.04. So round 1 of the sale should be on 19 or 20? Why there is still no information about it?
