First of all, I want to apologize if my English is not perfect.
Here's my problem:
I want to unsubscribe someone from a list on Mailchilmp when that person has an opt-out value on Salesforce?
I managed to build the zap and when I test it before activating it works. But when I do it in real conditions, the lead always stays "Subscribe" on Mailchimp.
Do you have any advice for me
