Hi, I'm trying to do a csv import to an address field in the customer record. I want to update a phone number. I made 2 csv files, one for the internal ID of the customer, and the other for the address label and the phone number that I want to update. but it doesn't change anything,, csv import doesn't have any errors, What did I do wrong? I selected "overwrite sublist" as well.

try mapping the address ID since address is a separate record, so if id for the address record is not mapped then updates wont work

Thank you , Sam ! I changed the label to internalID and it worked

Great!
