Still haven't heard anything about airdrop 4, despite contacting the dev here, on twitter, and on Telegram. I've read the requirements a number of times and seem to have met them, plus we discussed it on Telegram and no one could come up with a reason why I shouldn't have received it. I know a number of other people are in the same boat, and the lack of communication is extremely disheartening. In the early phases of a project two of the few things to judge the project on are meeting commitments and communication, and, I feel sad to say, GPlay is failing badly in both areas.
