I am trying to convert a bunch Dynamic Component Templates (for the reasons very well described here: Dynamic vs. Static Component Templates), and first I need to unpublish all the wrongly-published DCPs. There are a few CTs that are used in children publications (Mobile Web for example) and I am unpublishing it with the "Unpublish in Child Publications" within the Advanced Tab in the Publishing dialog, checked.
However the DCPs are not being unpublished from the children publications.
Is this the expected behavior? Shouldn't they unpbulish too?
Note: all children publications use the same publication target with the same target types.
