Browse Azure Storage: No media found

I’ve installed the plugin (4.1.1) and got it configured to my storage account. When I upload new images for a post, they are successfully uploaded to Azure Storage. However, when I choose the “Add Media From Azure” button and the “Browse Azure Storage” window appears, it doesn’t show any of the media that exists in the blob container. It shows nothing.

If I choose just “Add Media” instead of “Add Media From Azure”, I can find the stuff in my Media Library.

Why does “Browse Azure Storage” not see anything?
