I've finally understood exactly how to upload data using the S3 connector to and MDA object. however, I was quite surprised when I was troubleshooting and searching the gainsight support site that formats starting with day (dd/MM/yyyy or dd-MM-yyyy) are not at all supported. this becomes incredibly annoying for me and our CSMs since we're based in Europe and most of our data in Salesforce uses this formatting instead of the classic American MM/dd/yyyy. It would be very nice and much more manageable if we could have this format supported. Thank you

yes I'm sorry. it seems I must've had some other error that was messing up the formatting and it worked fine for later uploads.
