All of a sudden, CM is not importing any of the custom fields in my CSV file - just the email address. The sample values are displayed on the field mapping page, but once submitted, nothing gets imported (except email). Furthermore, when I attempt to edit an existing subscriber, the system won't even accept any values I manually enter into these fields (firstname and lastname).
There were some issues with importing custom field data earlier, but it should be fixed now. Just let us know if you're still having any problems. Our apologies for the issue and thanks for your patience while we fixed it.
