I've seen this with many app redesigns: the version that I initially downloaded and installed was a joy to use albeit a little rough around the edges in terms of appearance. In some subsequent update, the appearance changes to look very appealing, but after navigating around to find some previously killer function, it is nowhere to be found. A subsequent web search confirms my findings and fears that the feature that I previously relied upon no longer exists.

I'm not sure how to describe it: the best that I can come up with is that as something gains mass market appeal, the power users (on average the most vocal) are neglected by those they helped succeed in the marketplace.
