Signal issues

Long time pixel/nexus user here. Yesterday my pixel 8 pro started showing an exclamation mark in the cell signal on 5Ge on ATT - no service at work. I haven't had any problems until this week and I've had the phone since launch with no problems.

Anyone else have signal problems that just started? Maybe with the latest update?

So far I've done all the usual things like restarts, airplane mode, reset radios, hard restart, etc. The only thing I haven't done yet is factory reset, which will be my last resort.

Thanks in advance.
