Since beta 9.3 beta 1, I've been unable to turn on the "Text Message Forwarding" feature on my iPad Air. The result of this is that the iPad is only able to send and receive iMessages.
On the iPhone under Settings -> Messages -> Text Message Forwarding I see the iPad as an available device, but the button has been toggled off. Toggling the button to the on position brings up the dialog to enter the code it claims it will show on the iPad. No such code ever appears. I've updated to the new beta, have restarted both devices multiple times, logged out and back into iMessage, and logged out and back into iCloud (allowing it to delete everything), but nothing has changed.
Any suggestions? I've yet to do a restore, but I'm not convinced it will help, given the steps I've already gone through.
iPhone is a 5S A1453. iPad Air is a A1474.
