RegisterOnLaunch on iOS does not have any effect, fuse still register for push notifications at launch.
Tested on:
iOS 11.0.1 - emulator and device, on preview and released app.
Fuse 1.3.0
Thanks for reporting! An internal ticket has been logged and we’ll investigate.
Looking into this today and tomorrow. Push Notifications cannot be used from Apple’s simulator so there isn’t value testing there.
I’ll post news as I have it 
Yes Chris Bagley, you are right. But even on a real device this isn’t working.
Hi Chris Bagley, any news about this thread?
I can confirm it still not working
