I switched over to specifying other location on all file uploads in Cloud, it seems that Parent form location is not working any longer.
It completely ignores the parent folder ID of the parent form configuration, saving the file in the root of the repository.
Also it creates empty folders in the specified location in addition, just does not save anything there.
For example on this test form I have configured it like this:
If when submitting the form, I enter the folder ID for the path \Workflow, the following will happen;
It will create an empty folder called "Additional Path" under \Workflow but put nothing in it.
It will save the file upload to \Additional Path\UPLOADED FILE NAME
