Man I really wish it was back. I've read that they're working on making the new mobile web site faster but it will probably never be nearly as fast and streamlined and easy to use as the app. It's really a shame.
I think everything has been said that can be here. The app isn't feasible, and the mobile responsive site is. The app crashed regularly, didn't take advantage of new phone features, and every time it was updated, as many new bugs were introduced as were fixed.
