Visited yesterday, charged with M-CHARGE RFID without any issue.
The only thing that changed since 2023 seems to be the red skin on the charger that replaced the green skin. The parking spaces were not re-painted with the M-CHARGE branding. The sign above the parking entrance is still the same.
I didn't actually find the opening hours of the parking posted anywhere. In the M-CHARGE app there are hours, so it doesn't seem to be 24/7. There's a night entrance with a reader for the ticket, but it also says "Dauermieter" on the reader.
