So sometime in the past few months, I started noticing that the smart notifications to my Forerunner 630 were sporatic. Sometimes I would get them, but most of the time they don't come through. I've verified on the watch that smart notifications are turned on for both In Activity (sound and vibration) and out of activity (vibration only), as well as verified that the notifications on my iPhone 7s are completely turned on. Not sure what else to try.
