I seem unable to update an existing row in MobileConnect All Contacts list.
I also seem to not be the only one with the confusion:
My account seems to be set up correctly based on this known issue.
I have a single row in a source Data Extension:
And an Import Definition like so:
Which points to the source DE. The Contact Key field on the row in the source DE matches a Contact Key in the All Contacts list. I would expect it to then update the mobile contact with the new values but it does not. I.e., I would expect the highlighted fields (see below image) to now include the boolean values as seen in the source DE:
Contact builder looks like so:
Question is what am I missing here? Is Contact Key not the correct upsert key? I also see a field called Contact ID - is this instead it?
Edit: I am getting the following notification email with validation errors from SFMC:
"The following import has completed with validation errors" and the csv says required field _mobileNumber although the Mobile Number in my import is not empty:
Row Number Error Number Error Code Error Details Row Data
