Only Zappi and Ohme chargers I know, have delay charging enabled with a car running with the early2020 BMS update, as they (zappi and ohme) could be bothered to update their units, where rolec and co still continued to blamed MG, forcing MG to bring out SA015 BMS.
Easy way to check if car has that update: plug granny lead into car, but leave 3pin part out or switched off. Lock car. Wait 5mins. Then plug in 3pin/turn on switch. If it charges, then you got that updated BMS. If it doesn't charge then your BMS is production fresh.
