I don't live in the area and haven't driven through Canton, so I haven't used it. But others have. You can see multiple check-ins on
Plugshare from people with native CCS or CHAdeMO cars and also by Tesla drivers that had to use a CHAdeMO adapter. The most recent check-in was from a Leaf driver successfully charging via CHAdeMO two weeks ago (in mid-February). As for not seeing the location on your ChargePoint app, I'll repeat what I said in the message you replied to: check your filter settings and be sure that you have enabled the display of DC-CHAdeMO stations under Connector Type.
