Need to have SF Connector be able to interact and use data from API Version 38 or newer. See response from support below. Without this ability to interact with the newer API the connector cannot be used for all the reasons we spend money to use it for. Scheduling and Field service data is not able to be interacted with through the connector until this can happen.
"John has looped me in regarding your inability to use the Field type Service Appointment with our connector. I dug deeper into this field and found on the Salesforce API documentation that this field is currently only available on the Salesforce API version 38.0 and later. At this time our Salesforce Connector uses version 36.0. Which is why that field is not working as expected."
