Hello Paolo, could you explain more about what you are trying to do? What type of information are you trying to autofill?
When you are trying to autofill one thing you need to pay attention to is to use the [locked] configuration to make sure the person can’t change the information that was added.
If you are trying to autofill an email you can combine the default: email and locked configuration together, on your spreadsheet this configuration would look like this [default:email, locked]
