ATT NumberSync not working
I'm trying to get my Samsung Galaxy S10 phone and my Galaxy Watch 5 to successfully perform NumberSync without any luck. (Been trying for days now and have an open case with ATT Support, CM20221014_154858141).
The phone won't display a sync code and the watch gives me an error, "SD-SDK-400". This is a repeatable error but I can't find a resolution and ATT has not helped yet either.
I have an ID with ATT that is linked to my phone, Any help would be appreciated since I'm paying for this service and have a LTE watch.

Are you using Samsung's 'wear' app?
Are you signed into your Samsung account on the phone?

This was all done when I opened a case 5 days ago. Still am waiting on an update.
