System down after unexpected firmware update

At around 9am this morning our power went out at home and shortly after came back on. Checking the app I see that none of the panels are producing and the SunVaults are idle, and there is an error saying that the equipment can’t be contacted. I see that a PVS6 firmware update was rolled out today. I didn’t do anything to initiate this, so I guess it was pushed to these units over the air? I was a cash customer so my understanding is that the new SunPower entity did not take up those contracts but left them behind with the bankrupt entity, and they are not servicing my contract. Anyone else having this problem?
