Unfortunately, due to bugs in WatchOS, a number of our users are having difficulties with our watch app. Right now, the only thing to do is to keep trying the restart/reinstall process until it works. Other customers have reported success here. I'm sorry we can't offer any further help at present, but we're dependent upon Apple to provide further fixes.
Best wishes,
Adam
I received the EXACT same email from Adam and I agree it is pretty lame.
