Messing around with GNOME firmware for the first time . . . next to where is says "Attestation: Not OK" if I hit the "Store" button it asks if I want to update the cryptographic hash ("record current device cryptographic hases as verified"--how do I update it?

Yeah, it's not the most simple and user-friendly program out there. I guess it's primarily meant for more advanced use cases where you want to do more than just keeping your firmware up to date.
I have the same "Attestation: Not OK" on two different computers, I've decided to ignore it.
