We have been getting this error notification a few times:
Salesforce Sync Error: Required Field for Salesforce Sync is Not Visible
The following required fields are hidden from the Salesforce sync account

I am new to Marketo but from what I researched on the Community, it sounds like Opportunity fields are not considered sync fields. So why was it trying to sync over? I can't remove this field from the sync on the Marketo end. Does anybody have any advice on how to resolve the error?
