Well this is a bs Airdrop. First, it takes like 20 hours to receive the 0.1 Binance coin to be able to vote. Then, you vote and see a confirmation page for like, 1 second. I missed this window to take a screenshot. So I can't prove that I've voted for WePower. How am going to receive the 200 WePower tokens now? A lot of trouble for nothing.
This happened to me also.
In this case, you can just vote again and make a print-screen of the message " Already voted"
