Sorry for the confusion, it was stated in the livestream that local media wasn't supported at launch but would be coming. The main reason for this is that the sync system needs testing. That being said, many image based media types were enabled as local overrides (local media) in todays .34 update. As stated in the update notes, video media is coming next, but there are some additional options that need to be enabled in the back-end and some testing. The dev team is trying to test and harden one set of features at a time but mostly bug fixing atm 😉. And screenshots will be automatically utilized at some nearish point.
