My Vivoactive 4 is connected to my iPhone. I can see the phone notifications in the widget on my watch. I can ping the phone with the "find phone" feature on the watch. Garmin Connect on the phone is also showing that my watch is connected without issue. However, the notifications are not popping up on my watch when they are triggered on the phone. In other words, my iPhone alerts me with a notification, but the Vivoactive 4 does not alert me.
Everything had previously worked exactly as expected until I traveled on a plane. I've traveled before and not had this problem, so that may just be a coincidence. Do Not Disturb is off. I have power cycled the phone and watch. I removed the watch as a bluetooth device on the phone and re-added it. I even de-registered and re-registered the watch in Garmin Connect.
I'd prefer not to factory reset the watch, but that's the next step if the community doesn't have any suggestions.
