I've also noticed that USA-based users of CCS chargers often report needing to fiddle with the plug to get the car to charge.
Most of the reports I've seen are drivers of the e-Tron, Bolt and Setec CCS (for Tesla) adapter. They often report needing to put pressure on the handle while the station is handshaking with the car to avoid spurious ground isolation faults and/or communication errors. I don't recall reading anything similar with Teslas at Superchargers.
Given that this happens across manufacturers, I'm inclined to think that it is either a design flaw with CCS or a not-clearly-specified part of the CCS spec.
