I've been trying to map one of the Profile Attributes to a boolean field in Sales Cloud, but I'm getting the following message without any further explanation:
"That mapping is not allowed"
The original field in Sales Cloud is a true/false field, and it's synchronizing to MC along other fields we are using into a synched DE. I also tried restricting the values for this field to true/false, but it didn't help.
Did anyone else stumble upon this error?
