Abandoned by its Creator?

While this app used to be quite useful due to a slick UI, the app is currently unusable unless you enjoy looking through Popular or your Subscription Channel listings alone. It currently fails out with a data not in correct format for What to Watch, Subscription Videos, etc. This pretty much cripples the app for my usage to the point where even the official YouTube app is preferable.

Developers App Support link in the App Store is a dead link as well, leaving the impression this app is on life support and its Creator has left it to its fate.
