I'm stuck in the middle of switching from single-org to multi org.
In Marketing Cloud Setup > Salesforce Integration, I am getting the following error:
An exception occurred while saving the integration.
I am aware that it usually has something to do with the Sales Cloud API user's permissions, so I verified that the following:
- Marketing Cloud Connected App permission set has been assigned
- Marketing Cloud for AppExchange Admin flag is checked on user
- Marketing Cloud for AppExchange User flag is also checked
I cleared out user mappings and OAuth tokens in Sales Cloud for all my API users. Didn't have any problems with establishing the connection from Sales Cloud to Marketing Cloud.
I also verified that we have white-listed all Salesforce IP ranges for the Salesforce integration.
Any clues what might be missing here?
