My cast and crew list contains both email and phone numbers. During the upload process, both are listed but when editing is complete, some or all of the phone numbers are no longer there.
The platform collects the minimum information needed. If an email address is provided in the uploaded data, the corresponding phone number is not saved.
Phone numbers are only used to initially contact a contributor when no email address is available.
Contributors who have only provided a phone number will be asked to provide an email address when they complete the survey.
