Unfortunately, these troubleshooting steps don’t resolve the issue for those affected after the December software update. For several of us, that update appears to break home AC charging entirely.
I went through all of these steps back in December after installing a Tesla Wall Connector...
Still no update here in Chicago. Car has been at the dealer for last 19 days; no fix, no ETA, and no supervisor follow-up from Porsche NA after escalation.
Adding my data point for tracking purposes:

Charger at Home:
Porsche Universal Charger (NEMA 14-50, not hardwired)
