TL;DR: App broken, fix coming this weekend. AdSense API we were using has been replaced by a newer version. App will be updated this weekend with fixes and new features. In the meantime, use the Google Adsense app in the Android Market.
So since I write that last message, I found myself with an unusual job offer; I left the AdSense team in London, which I've been on for years, and moved to Mountain View to run the Display portion of the AdWords frontend and help advertisers make sense of our display ads business.
So my life has been a bit upside-down lately, and that's meant I've had very little time to launch the version of the app that wouldn't have broken when the rest of the AdSense API team did their launch. Most of my life is still in boxes, there's IKEA furniture stacked in little flat-pack cardboard boxes in our new house in Noe Valley, and the dog sees me for about three hours a day.
None of those things are excuses for having failed to deliver you an update, but I hope they go some way into explaining why it didn't happen in time.
I'm very sorry the AdSense Dashboard isn't working for you today. I'm going to fix this very soon - this weekend - and will iterate a few times over the weekend to clean up a few long-standing bugs and handle a few errors and crashes that the occasional person has reported.
Now, it's important to state clearly that this app isn't going to live forever. I really want everyone to migrate to the official app - I worked hard to get approval for that team to get officially sanctioned and to build the best possible user experience for you and the rest of our AdSense users, and they're working hard to build out a fantastic feature set, and already has features I don't offer, like notifications. If that app has the feature set you're happy with, switch now; if it doesn't, tell them what you most wish it had by providing feedback on the app, which they're watching closely.
I miss my old team. I'm so proud of the app they've built, and the UX team has done an amazing job of making something not just functional but beautiful. Now's a great time to go and try their app - again, if you haven't used it recently - and remind yourself of what having full time engineering on making a great user experience can achieve, rather than some guy in his 20% time.
