I did not pay much attention to the nozzle, but they should be quite standard, I guess... I tried many gas station and have the same problem. I also tried sticking the nozzle further in or our, no difference.
I also tried pulling the nozzle as much out as possible so that the main inlet of the gas tank is open to the air (that's how I see the foam), but as soon as the foam comes up, the nozzle shut off.
I have not tried mannually fill yet, I will give it a try and follow up here. Thanks!
