I'm importing contacts from a legacy system and am running into a wall importing addresses from non-US countries. For instance, for Canada, I'm trying to import a Canadian province. I've tried both the full name and the two-character abbreviation (e.g. "Saskatchewan" or "SK") and neither works. I have confirmed that the provinces are correctly included in the civicrm_state_province database table. The import error states:
Invalid value for field(s) : State
What am I doing wrong?
