I'm surprised that you CAN insert a CF card the wrong way in a 7DII (without reeeeaaaallllyyyyy forcing it). On my EOS 40D, the card will only go in one way. The card has side rails that have to match direction on the slot. Same thing on my multiple CF card readers.
It would be like trying to insert a USB A plug upside down into a computer. If you try hard enough you can, breaking things at the same time.
I can't physically insert a CF the wrong way into a 5D3 without knowing something is wrong before it reaches any pins. Maybe I've been lucky but I would have thought the immediate resistance would be felt. Best of luck with the fix.
