Razer Nabu iOS Authorisation

I'm trying to setup a test iOS app to see what I can do with the Razer Nabu but I'm struggling with the patchy documentation. The example for authentication only mentions a 'fitness' scope and with that I don't seem to be able to send a notification to the band (the main thing I'd like to try). When I try and send a notification I get Operation 36 returned and no notification on the band so I assume that means it failed (return codes from the SDK aren't documented it seems). Does anyone know if there is a different scope for notifications? I tried 'notification' and 'notifications' but they resulted in failure to authorise in the Nabu Utility app. Any help or pointers to documentation/samples/guides I might have missed would be very helpful! NB I managed to get authorised with the 'fitness' scope and read some fitness data so everything's working except for the notifications!
