App itself and Notification Center works great but the Watch OS 2 Complication has issues updating. This is using the latest update, it updates once (when you set it) then needs to be manually tapped on to open the Watch App then, a firm press to "refresh" then, itll update once you Digital Crown out to the main face again. Please fix. May request refund.
