When I run Connect and pull down our Opportunities data, there are missing custom fields. In total, we have 105 custom Opportunities fields, but the resultant dataset contains only 76 of them. Not coincidentally, the missing 29 were all created at the same time, as part of a customization done in March 2018.
I restored a backup file and looked at the opportunities_cstm table to make sure the fields were actually there, and they are.
What is prevernting these fields from being included in the result set?
