Apple Watch Smart Alarm has been removed with IOS 10.1.1
I have recently updated my series 8 from its original IOS to 10.1.1. The smart sleep app that wakes me up within the 20 min window depending on sleep cycle has disappeared. One of the reasons I got the watch was because of this feature. Is it that I have to activate this app from somewhere else or has been removed completely? If removed, how can I get it back ie install the previous version of the IOS.
