MC4SF_LICENCE_COUNT_ERROR

What this means: Mailchimp for Salesforce could not count the members in your audiences when refreshing licence usage. Billing and licence checks rely on this count, so the number shown in Settings may be out of date until the next successful refresh.

What to do: Confirm the primary sync user still has the Mailchimp Admin permission set. Check that your Mailchimp account is still connected under General Settings. Review the associated Maintenance message. If the warning continues, contact Beaufort 12 support.
