Existing device (Fenix6) "over-written" when trying to add a new device (S2 scale)

I would try following the steps in this article - https://support.garmin.com/en-US/?faq=A5iUlhpQaY1tm57RQoFxE6

Be sure to remove all mentions of the Fenix  6 or Index Scale (both in the app and in your phones Bluetooth settings) then try and add the devices back one at a time

If that doesn't resolve your issue, please contact Garmin Support for the most efficient and detailed assistance

Removed both devices and uninstalled Garmin Connect app. Rebooted phone. Added Fenix no problem. Have spent 3 hours trying to get the scale to pair with a phone -- any phone, I tried three -- and always end up with "pairing failed - setup not successful. Factor reset etc. doesn't work.

While troubleshooting this problem I see multiple threads going back four years about the same issues.

Contacted Garmin and they want me to ship them the device at my own expense. Astounding. Last Garmin purchase.
