When importing a CSV file, you must first upload the media items into the platform, so they can be associated and assigned to the title.
To upload media items, perform the following steps:
Open the Media Items menu and select Create New. The drop-down options are displayed.
Select Add Media. The Add Media Item modal is displayed.
Drag and drop the files you want to upload or click to browse for files. The upload process begins.
Once all files have been successfully uploaded, select DONE. The media items are now uploaded into Connect and their ingest process has started.
