Maybe you didn't qualify for the second airdrop! In this case the first airdrop will be delivered tomorrow - I suspect.
Okay, didn't know that they distributed the second round at first. In this case, I know why I haven't received anything yet.
No, the people who have qualified for both airdrops received both together - not only the second one.
It is not to late to send 0.0001 Waves to this address: 3PBNiHBcp8rxiYkGVGNHEGZHEamb1aXeWVv to partizipate in in the second airdrop! too.
