Thanks josephyancey! I verified that ordering the media on the page instead of in the media library works for me as well. I checked the traffic on the media picker at the page level, and it is including both a Post ID and a nonce value with the request. I’m assuming the problem is with one of those two values when ordering in the media library. This is really the only problem I have encountered so far with this plugin. Other than that, it seems to be working really well!
