I am having an issue with the deletion of a flow version. Using standard declarative ways the version will not delete and removing the flow all together gives an internal service error so I have been attempting to delete it via the workbench. However I keep getting an error "Problem: setup object in use" I cant seem to find a resolution I have attempted to; deactivate it / remove from all lightning pages but i cant find out where its still in use at.
does anyone know what this error specifically refers to? below is my destructiveChanges.xml info
