Keep an eye on https://groups.google.com/forum/?fromgroups#!forum/nfc-ring-beta-testers it's the beta testers group, perhaps comment on your issues there too.
There's going to be a short delay on Alpha ring pre orders in case they're needed for exchange purposes. It shouldn't be too long and I'm sure John will make an announcement when it's going to happen.
@John what fixed the problem?
Hi mate, you wouldn't want to add those to the github would you? https://github.com/mclear/Android_NFC_Ring_Unlock
That's a bit of a pain. Well, give support a yell and let them know it's quit on you again mate.
