Hi.
Just added Pushbullet to the Connect. And it identify it’s self as NzbDrone and not Sonarr.
No biggie, but now you know 
Found out that it’s the test that identify as NzbDrone and not the Downloaded notification.
Its still a work in progress, we do expect a number of these cases to come up in the coming weeks though, but nothing to be concerned about, we’ll be fixing them in groups.
