I have a document library in SP Online site and it has two content types associated. There is a list level field/column that is associated with one of the content type.
Content Type 1 - Document
Content Type 2 - Custom Document
List level column - Department
There are lot of records in this library that got migrated from other system. Now, we have observed that the list level column is associated with wrong content type (Content Type 1) that is associated with the library.
Is there any option to change the association of List level column to Content Type 2 from Content Type 1 using PS Script or C#.
