The Bluetooth option has vanished from the Connect App settings and the watch can no longer communicate. The app was updated 2 days ago and since then I have the problem.
Anyone else with same problem?

I received an iPhone software update 2 days ago. I paused the update. Garmin's iPhone Options Bluetooth toggle disappeared. I finally ran Apple's iPhone update just now. Garmin's iPhone Options Bluetooth toggle then reappeared and Garmin Connect connected and synched via Bluetooth to my Garmin. Back to normal.
