Since the latest app update. I have updated IOS and updated the app but now I can not get my vivoactive 3 to pair to Bluetooth or sync. Have done all the trouble shooting ideas a number times turning off Garmin the phone and signing out of app. Still not working.
Make sure you're doing a complete unpair/pair of the device from the app using the steps below.
Verify you have all updates by connecting your watch with USB cable and sync using Garmin Express.
You said you updated Garmin Connect, but a new update just came out today. Might want to double check.
If still no joy, contact Garmin Support Center https://support.garmin.com
