Note 8 not receiving updates - What to do?

AT&T Note 8 - purchased directly from AT&T

Stock - no changes/modifications

Baseband Version: N950USQU4CRD7

Build number: R16NW.N950USQU4CRD7

Android Security Patch: April 1, 2018

Looking at AT&T's updated history logs, my Note 8 seems to be stuck with the last update being the May 15, 2018 update. I just realized this as I've been seeing people talk about updates received and some emoji feature - which I don't have. I keep checking my device and it continuously says my current software is up to date - no updates available.

Thought about doing a Format/Hard Reset and starting fresh... but would that help my situation to receive the latest update? Not sure it would help at all or what to do.

Any help is appreciated.

Thanks!
