AT&T NumberSync stopped working on my Galaxy Watch 4
I've been using my Galaxy Watch 4 with NumberSync enabled from my primary phone. It was working well until 2 days back, now I'm trying to make it work, but it keeps throwing an error. Logged into my AT&T account and confirmed my watch is not listed under Synced wearables. When I tried to reconfigure the NumberSync, it prompts for the code from my watch, and my watch AT&T NumberSync app throws an error with code PD-SD-N/A. No luck with support chats/calls. Anyone have similar issues recently? I did get a text confirmation saying that my NumberSync stopped working 2 days back, and that's when I realized it doesn't work. So, when AT&T have these services traced in the backend, it'd be good at least if they also stop charging us for the watch line for the time when NumberSync doesn't work.
