On my watch I get notifications for SMS but can only view and dismiss, I cannot reply and they are not saved in the message app. If I get an iMessage then I get the option to reply and also the message is saved in the message app. Having spoken to Apple apparently this is 'expected behaviour'. If that's the case then the watch is going back as I don't see the point in not being able to reply to all messages?! Is anyone else able to respond to SMS messages on their watch or is the info I've had from support correct?
