Visited yesterday and did a short charge with M-CHARGE RFID, no issue.
Based on the location of the M-CHARGE marker I was pretty sure the charger would be in P1, but there isn't a single sign on location. Even after entering P1, you can see almost the entire floor and still the chargers are not visible, because they are hidden in the only corner not visible from the entrance. You really must be looking for them, or you'll never know they exist.
The opening hours of the parking don't seem to be indicated. It probably closes with the store. I don't know if the outdoor parking that's behind the same gate stays open after closing time, but it doesn't change anything as the chargers are inside where it most certainly closes.
I'm surprised there were people parked in the spots opposite the charger. Those don't look convenient at all. The parking was very lightly used. Any parking spot in the middle of the parking would have been just as close to the entrance and much faster to leave the parking when done. Seems like I'll never understand the mind of the average car-centric shopper.
