In addition to the above the slow rates could be down to the charger itself throttling it rather than the car.
VAG uses 400v architecture, some chargers only pump put their advertised at 800v odd.
Although the smaller battery has a slower charge rate than the larger type its not that much slower end to end because its smaller. Of the handful of times I have charged publically, I was typically getting the 65 to 50 you state Wizard in the 58kWh ID3 but eventually saw the 110kw rate on way back from Norfolk getting down to 10% and a good run on a warm day, on a Shell ultra 175kw rapid. You'll see it eventually.
