Content that is assigned to a Bundle will be automatically ordered based on their Upload Date so it is good to keep in mind that the ordering cannot be changed manually at the moment. If this is something that would be important to you, please send us a feature suggestion about it!
This is specifically for Content accessed through Bundles that will appear within the “My Library” portion of the Catalog:
In the example above, the “A Crying Galaxy” video is ordered as the second video in the Bundle while on the Bundle Edit page, you can see that the video was instead assigned last.
This is due to the “A Crying Galaxy” video having been uploaded after all 3 videos before it within the “My Library” portion of the catalog.
