Is there a way to send push notifications to one device? I know a workaround for this is text message option, but is there a native way to select or exclude a device from push notifications?
You can do this with contact book and user accounts. I know that those aren’t completely rolled out to everyone yet. So the answer is yes, but not yet, for some people. 
Oh ok, I just found a thread regarding the contact book feature, looks like it’s something they are working on. Text will have to do for now I suppose, but it’s slightly slower than notification push.
