I have a similar problem to the person in the post below. I have single-option custom fields in Pipedrive, and when I use Zapier to update Mailchimp with data from those custom fields, I only get their IDs and not their values (e.g. instead of Option1 as the value, I only see the ID number, e.g. 20). The post below (10 months old) suggests that the problem has been fixed, but not for me. Does anyone else know how this can be resolved?
