Push notifications did
work previously. My guess is that GW's notification server is screwed up -- the server for another of my push notification services had a problem that was fixed today. If that's the case, then there's nothing wrong with the app.
I'd suggest that affected users follow the instructions
given by GW, including the instruction to send them your device's UDID
when all else fails.Update:
I didn't wait long enough before posting this message otherwise I'd have mentioned then that push notifications are once again working for me. No idea what changed.
