Can't add album artwork manually, in 12.2.
Is anyone else having trouble manually adding album artwork, since version 12.2.x.x of iTunes for Mac? I have created a basic PNG like always and have tried both drag and dropping the art onto the Artwork panel, in the Info dialog for a song, as well as clicking the Add Artwork button, navigating to the image, and selecting it. Both methods appear to update the Artwork panel in the Info dialog, but the artwork simply disappears after clicking OK.
