Minimum clearance violation with JLCPCB - discrepancy between original and production gerber?

Still wonder why they’re flagging it now.

Percentage of copper between layers less than 30%

I don’t know for a fact but I think not . . . a “Maker” I follow on YouTube had to go through the same thing recently when JLCPBC changed their specs, all of a sudden boards they had made for him previously were no longer to their spec. He ended up doing some significant layout mods using their new clearances on several of his boards.

Other JLCPBC customers have had to make significant board changes recently to accomodate JLCPCB spec changes.
