We're also seeing this problem and submitted a bug report (FB13130970). If you haven't done it yet, I suggest you do it too so it gets more awareness at Apple. Let's hope this gets fixed before the final release.

I also think this is broken and quite confusing. Our watchOS app makes network requests just as our iOS one does. I don't get why we can get the status of the connection on iOS, in order to avoid making unnecessary requests, but not on watchOS. This API should be available to every watchOS app, but, if that's not possible for whatever reason, the documentation of NWPathMonitor or NWPath should point out that it's only available for audio streaming apps.
