I have the following situation:
- I've created several site columns en site content types
- I've created several sub webs with list, inheriting these content types
I assumed that if I updated the site content types it would be propagated to all inheriting content types. Now sometimes this is the case, but more often the changes are not propagated to the inheriting content types.
Both changes done manually and through CSOM are not propagated. The content type that I have the most issue with is based on a task content type.
If I create a new library with the content type, all is well. This new library inherits the right settings.
I have a dev and test/production in two tenants and three site collections. On test and production I have about 250 webs, inheriting these content types. I have these issue in both dev, test and production. So it's not unique to one tenant or site collection. I'm using Office365.
Does anybody have any experience with this, and knows how to solve and/or prevent this issue.
